摘要：
A temperature sensor (60) is placed positionally corresponding to a central portion of a shunt resistor portion (SR). According to the configuration, it is possible to detect an approximately average temperature of the shunt resistor portion (SR) while avoiding a temperature biased in the temperature distribution in the shunt resistor portion (SR). As a result, the temperature of the shunt resistor portion which is the base of the resistance is reliably detected to enable the accuracy of current detection to be improved.
