Embodiment Construction
[0023] Below, refer to figure 1 and figure 2 A first embodiment of the temperature sensor of the present invention will be described. In addition, in each drawing used for the following description, in order to make each member recognizable or easily recognizable, the scale is changed suitably.
[0024] like figure 1 and figure 2 As shown, the temperature sensor 1 of this embodiment is used, for example, to measure the temperature of an electronic device 2 that generates heat during operation. between the substrates 3 , and conduct the heat of the electronic device 2 to the substrate 3 ;
[0025] The above-mentioned electronic device 2 is, for example, a transistor such as a power transistor or a power FET. That is, when the electronic device 2 is a transistor, the temperature sensor 1 of this embodiment measures the junction temperature for driving control of the transistor.
[0026] The above-mentioned substrate 3 is, for example, a printed substrate formed with patt...
