であった。However, when the terminal 102 is made of metal like the above-mentioned electrode material, the lower end of the terminal 102 that comes into contact with the conductive gel layer 103 is included in the conductive gel layer 103. There was a problem of corrosion due to moisture and ionic compounds. For this reason, countermeasures such as providing an anticorrosion paint layer 105 at the lower end of the terminal 102 and attaching an anticorrosion film thereto are taken. However, moisture or an ionic compound is formed between the flange 102a of the terminal 102 and the conductive sheet. There was a possibility that the terminal 102 would corrode by penetrating into the contact surface with the support 101, and the anticorrosion effect was hardly sufficient.

を容易且つ精度良く行うことができるようになる。[0011] Such a convex terminal made of a conductive non-metal generally has less mechanical strength and abrasion resistance than a metal terminal, but in a preferred embodiment, it is located above the flange of the convex terminal. Since the metal cap is attached to the portion to protect and reinforce the convex terminal, there is almost no fear that the convex terminal will be damaged or worn when the conductor cord is connected or disconnected. In particular, on the upper part of the convex terminal projecting from the base material sheet, a metal cap provided with a flange at the lower end is attached,
In the case where the base sheet and the conductive layer around the terminal insertion hole are sandwiched from above and below by the flange of the cap and the flange of the convex terminal, damage and wear of the upper part of the convex terminal can be prevented in the same manner as described above. In addition, it is possible to firmly attach and fix the convex terminal without rattling by the clamping force between the flanges.
Further, an insulating film having an area larger than that of the lower surface of the convex terminal is attached to the lower surface of the convex terminal and a conductive layer therearound. Since the current stops flowing through the insulating film, it is possible to eliminate the electrical stimulation caused by the direct current. Moreover, when such an insulating film is adhered, the convex terminals are fixed, so that the convex terminals may fall off from the terminal insertion holes before the conductive adhesive layer is laminated, or the convex terminals may be displaced or tilted. Does not occur, and the assembling work of the electrode material can be performed easily and accurately.

きるようになる。Further, the electrode material according to the second invention is such that the convex terminal is formed by joining and integrating a lower terminal made of a conductive nonmetal having a flange at a lower end and an upper terminal made of a metal. Therefore, there is no need to worry about corrosion even if the lower part of the conductive non-metallic terminal is in contact with the conductive adhesive layer containing moisture or ionic compounds.Moreover, since the upper part of the terminal is made of metal, it is possible to connect a conductor cord. There is almost no fear that the top of the terminal will be damaged or worn when it is removed. And the thing which attached the insulating film larger in area than the lower surface of this convex terminal to the lower surface of the convex terminal and the surrounding conductive layer eliminates electric stimulation by the electric current directly from the terminal lower surface similarly to the above. Thus, the assembling work of the electrode material can be easily and accurately performed.

A soft synthetic resin sheet (including a film) of about μm is used, for example, polyethylene terephthalate (PET)
For example, a polyester sheet, a polyurethane sheet, or the like is preferably used. In particular, a transparent non-crosslinked polyurethane sheet having an elastic modulus of about 30 to 350 kg / cm 2 and a thickness of about 50 to 200 μm, which has been subjected to an antioxidant treatment so as not to yellow, has excellent flexibility and moderate Since it has high flexibility, it adheres to the movement of the skin when applied to the skin at the bent part of the human body and does not easily peel off from the skin.

A convex terminal having an electric resistance of more than 1Ω is not suitable for a terminal of this kind of electrode material through which a minute current flows because the electric resistance is too large. A preferable specific example of the convex terminal 2 is one obtained by cutting lump carbon into a terminal shape as shown in the figure, or a resin in which a large amount of carbon powder or graphite powder is mixed so that the electric resistance is 1 Ω or less. And those molded by injection molding. Even if such a conductive non-metallic convex terminal 2 comes into contact with moisture or an ionic compound contained in the conductive adhesive layer 4, there is no need to worry about corrosion as in the case of a conventional metal terminal.
