摘要：PURPOSE:To decrease the fluctuation in the temp. of a gas sensitive body and to prevent the degradation in characteristics and yield by providing conductive leads with heat radiating parts for controlling the temp. of the gas sensitive body which are arbitrarily cut and removed according to the temp. states of the gas sensitive body. CONSTITUTION:The leads 9a, 9b for electrodes and the leads 10a, 10b for heaters consist of blank materials, such as nickel and extend nearly perpendicularly from the two sides 11a, 11b of a leaf frame 11 toward the central side. The respective leads 9a, 9b, 10a, 10b are integrally provided with the heat radiating parts 12a to 12d for controlling the temp. of the gas sensitive body. The heat radiating parts 12a to 12d are made of rectangular plates and are coupled via the fine width parts 13a to 13d thereof to the respective leads 9a, 9b, 10a, 10b in such a manner that heat can be transferred. The heat radiating parts 12a to 12d are so set that the volume (surface area) thereof is 1/4 the volume (surface area) of the leads 9a, 9b, 10a, 10b. If, therefore, the heat radiation quantity form, for example, a piece of the lead is assumed to correspond to the quantity to lower the temp. of the gas sensitive part 1 by about 20 deg.C, the temp. of the gas sensitive part 1 can be increased by about 5 deg.C by cutting the one heat radiating part.
