PURPOSE:To produce a small-sized and long life temperature detecing element provided with high characteristics and high productivity by using the inductance variation of an amophous alloy magnetic substance of which magnetic characteristic is suddenly changed at the border of its curie point. CONSTITUTION:An amorphous alloy magnetic wire 2 consisting of Fe, N, Si, and B e.g. of which inductance is suddenly reduced at the temperature more than it curie point is incorporated in a cylindrical case 1 composed of aluminum or the like having high heat transmissibility so as to be folded back to detect the curie temperature as the change of inductance. Said configuration makes it possible to produce a long life and easily producible temperature detecting element having superior characteristics such as high responce and the high degree of applicating freedom. |
