端と端子１３′とを接続する導体である。 FIG. 2 shows an exploded perspective view of the main parts of a capacitor element, in which 6 is an electrode foil, 7 is a dielectric film, 8 is an insulating film such as polypropylene or polyethylene terephthalate, 9 is thermocompression bonded to the insulating film 8,
A temperature fuse integrally formed by vapor deposition, etc. As shown in FIG.
and a capacitor element 10 are connected in series and housed in a resin case 11, filled with a resin 12 such as epoxy and sealed, and completed as shown in FIG. Reference numeral 9' indicates a connecting portion at both ends of the temperature fuse 9, 13 and 13' are terminals, 14 is an insulating separator, and 15 is a conductor connecting one end of the temperature fuse connecting portion 9' and the terminal 13'.
本考案は以上のようにして構成されているので
