Claim:
1. A semiconductor device comprising: a semiconductor substrate having an element; a front surface electrode that is electrically connected to the element and disposed on a front surface of the semiconductor substrate; a rear surface electrode that is electrically connected to the element and disposed on a rear surface of the semiconductor substrate opposite to the front surface; a protective film that is disposed on the front surface of the semiconductor substrate in a separation region; and a temperature sensor that is disposed on a front surface side of the semiconductor substrate, wherein: the front surface electrode is divided into a plurality of pieces along at least two directions on the front surface with the protective film in the separation region; the separation region includes an opposing region located between opposing sides of divided pieces of the front surface electrode, which are adjacent to each other, and an intersection region, at which the opposing region intersects; the temperature sensor is disposed in only the opposing region; the at least two directions are a row direction and a column direction orthogonal to each other on the front surface; and the front surface electrode is divided into the plurality of pieces along the row direction and the column direction.
