により検出端子５ａはその先端部。That is, the lead wire 9 of the detection terminal 5a is covered with a thermoplastic resin tube 6 that protrudes several mm from the end of the lead wire 9, and the end of the lead wire 9 is closed in the tube 6 that protrudes several mm and is heated. It is filled with plastic resin powder 7 (see FIG. 2). Next, the tube 6 provided protruding from the end of the lead wire 9 and the powder 7 filled in the protruding tube 6 are simultaneously heat-fused to form a heat-fused body.8. (see FIG. 1), and for this thermoplastic 1W14 resin, a material having electrical insulation properties and excellent heat resistance and acid resistance, such as a fluororesin, was used. That is, a heat-shrinkable tube 6 made of a fluororesin and a powder 7 made of the same fluororesin are used in this manner. Therefore, the detection terminal 5a is at its tip.
