構造を示す。The secondary ignition odor that applies to these requirements is the one that connects the tips of two lead wires with a fine and extremely short resistor (for example, platinum wire or nichrome wire). be. However, in the igniter having such a structure, since the resistor is thin and short, it is extremely difficult to connect it to the tip of the lead wire. In particular, if the length of the resistor is less than one cape, it becomes difficult to see it directly with the naked eye, making it almost impossible to manufacture it. The igniter of the present invention includes:
Unlike such conventional devices, this device is easy to manufacture, has high ignition reliability, and has a structure suitable as a micro igniter. An example of the structure of the igniter of the present invention is shown in the drawings. The drawing shows two metal foils 2, 2 bonded to the surface of an insulating film or sheet 1 with a required spacing, the metal foils 2, 2 being connected by a resistor 3, and the metal A structure in which lead wires 4, 4 are connected to foils 2, 2 is shown.

5) Connect lead wires and resistors (platinum wire, tungsten wire, etc.) to the metal foil portion by adhesive or welding. In this case, to connect the lead wire to the metal foil, make a pongee hole at a predetermined location in the film or sheet, insert the lead wire through the hole from the back side to the front surface, and then connect the tip of the lead wire to the metal foil. It can also be done by connecting to. '61 Cutting a film or sheet according to a pattern formed on the surface of the film or sheet.
