Abstract

PURPOSE:To maintain good the thermal responsibility of a heat generating resistor, by specifically determining the ratio between the length and the outer diameter of an inorganic cylindrical member of the heat generating resistor and also the ratio between the inner and outer diameters thereof. CONSTITUTION:A core wire made of molybdenum or the like is wound by platinum coils 1a and 1b, and provided with a lead wire 2 by welding and baked with an aluminum layer 1c thereonto by electrophoresis. Then, the core wire is removed by dissolution, whereby a heat generating resistor 1 is obtained. At this time, the aluminum layer 1c in a cylindrical shape is so formed as to establish lE/dEo>=10 and dEo/dEi>=2 wherein lE, dEo and dEi respectively represent the length, the outer diameter and the inner diameter of the aluminum layer 1c. Accordingly, since the heat transmission in the outer peripheral portion of the heat generating resistor 1 and also the heat conduction within the resistor 1 can be set in good balance, the thermal responsibility of the resistor 1 can be maintained good.
