PURPOSE:To enable stable temperature measurement and to decrease the number of processes and the time required for attaching a temperature sensor, by providing a heat sink with a path through which the temperature sensing section of the sensor is inserted to be close to the heat dissipating surface of a heat generating body when the heat generating body is mounted on the heat sink. CONSTITUTION:A transistor 2 is attached to a heat sink 1 by means of a mounting screw 3 such that the heat dissipating surface of the transistor 2 is closely contacted with the attaching surface 1b of the heat sink l. In order to measure a temperature, a heat-conducting compound is injected into a through hole la in the heat sink 1 and a heat sensing section of a temperature sensor is inserted therein. In this manner, the temperature can be measured easily and stably. |
