る。FIG. 1 is a perspective view of a main part of an embodiment of the present invention, in which terminals 1 and 2 facing each other are soldered with a solder 3. FIG. 2 is a sectional view taken along the line AA 'in FIG. As shown in FIG. 4, the terminal 1 has a shape with a narrow central portion,
That is, it has an hourglass shape and has an overhang structure in which the base film 7 is not present in the soldering terminal portion.
Since the terminal 1 has a drum shape, the solder wettability of the terminals 1 and 2 is not limited to the solder wettability of the minute portions on the side surfaces of the terminals 1 and 2, and the terminal 1 has a drum shape. The soldering state can be easily determined by observing the wetness of the solder in the portion where the central portion is thin and the shape in which the hem of the solder 3 is drawn. Therefore, the soldering work is facilitated and the working time is shortened. It Also, the certainty of soldering,
Quality level is improved and inspection work time is shortened. Further, as a merit of the hourglass shape of the terminal 1, since the terminal width is gradually narrowed from both side portions toward the central portion, the strength of the terminal after soldering is straight in the terminal width of both side portions. The strength is almost the same as that of the conventional terminal. Therefore, even when the soldering terminal has a finer pitch, the soldering strength is sufficiently secured, the soldering work is easy, the soldering can be performed in a short time, and the soldering quality is sufficiently secured.

4 has a drum shape similar to that of the terminal in FIG. 4, but the base film 7 has a drum shape similar to the terminal 1 up to the soldering terminal portion. That is, since the terminal width of the center portion of the soldering terminal is narrow, when soldering is performed, not only the side surface of the terminal but also the thin portion of the center portion are wetted by the solder as in the embodiment of FIG. The soldering state can be easily determined by looking at the state where the bottom of the solder is pulled. Therefore, the soldering work is facilitated and the working time is shortened. Further, the reliability of soldering and the quality level are improved, and the inspection work time is shortened. Further, as in the embodiment of FIG. 4, it is also effective as a fine pitch soldering terminal. In the above embodiment, the shape of the terminal 1 is a drum shape, but the shape is not limited to this shape, and at least a part of the terminal 1 becomes narrow or is notched in the area where the terminals are soldered and joined. With the shape, the same effect as in the above embodiment can be obtained.

Also, the certainty of connection and the quality level are improved. Furthermore, since the base film is provided so as to overlap the plurality of terminals, it is possible to prevent the terminals from being separated.
