Abstract
The accuracy of measuring the temperature of a semiconductor element is improved, while a method for measuring the temperature using a general-purpose semiconductor element is provided at low cost. A fourth conductor that is a part of a first conductor connected to a power semiconductor element and is a thin line pattern extends under a chip thermometer. The fourth conductor and the thermometer are connected to each other through high thermal conductive resin.
