A semiconductor device that is equipped with a semiconductor substrate, a composite metal film, and a detection terminal is provided. The composite metal film is formed on a surface or a back face of the semiconductor substrate, and has a first metal film, and a second metal film that is joined to the first metal film and is different in Seebeck coefficient from the first metal film. The detection terminal can detect a potential difference between the first metal film and the second metal film. |
