Patent ID: 7663469

Claim:
A thermistor device comprising: a thermistor element unit having lead conductors at both ends in a length direction of said thermistor element unit; a pair of terminal plates; and a resin, wherein said lead conductors are drawn out from both ends of said thermistor element unit to extend opposite to each other in said length direction, and curved to have bends at intermediate portions between proximal ends and distal ends, said distal ends extending along a height direction perpendicular to said length direction, each of said pair of terminal plates includes connecting portions disposed at both ends of said thermistor element unit in said length direction, said connecting portions project from one end of each of said pair of terminal plates along said height direction, said distal ends of said lead conductors are aligned with said connecting portions, respectively, outside plate portions of each of said pair of terminal plates, and joined together in an alloyed state by welding, said distal ends of said lead conductors and said connecting portions are welded together into a spherical shape, and said resin covers said thermistor element unit, and said distal ends of said lead conductors welded to said connecting portions.
