めて向上できるようになる。Function: In this positive temperature coefficient thermistor device, the terminal pieces protruding from the through-holes of the porcelain case toward the back side are shifted closer to the diagonal line of one corner than the center line perpendicular to each terminal piece, and spaced apart from each other. Since the terminal pieces protrude from the back side of the terminal, the terminal pieces can be positioned far apart from each other, thereby providing a sufficient creepage distance between them. In addition, since each bent claw is folded and locked on the back side of the porcelain case from the side of the porcelain case away from the protruding position of the terminal piece of each electrode plate, the creepage distance between each terminal piece and the bent claw can be increased. This makes it possible to significantly improve the dielectric strength voltage.

The terminal pieces of the porcelain case are shifted closer to the diagonal line of one corner than the center line perpendicular to each terminal piece of the porcelain case, and are positioned protruding from the back side of the porcelain case, and the electrode plate and thermistor element of this porcelain case are A heat dissipation plate that transfers heat from the thermistor element via an insulating plate is placed on the open upper surface of the accommodated recess, and the bent claws provided on both sides of the heat dissipation plate are inserted from the positions where the terminal pieces of each electrode plate protrude. A positive temperature coefficient thermistor device characterized in that a heat dissipation plate is adhered and fixed to a porcelain case by folding and locking the heat dissipation plate from the side part of the porcelain case to the back side of the porcelain case.
