Abstract
A semiconductor device includes a semiconductor element having main electrodes on opposite faces opposite in a predetermined direction, a substrate, and a sealing body containing resin. The substrate has an insulating base member, a front-face metal body on a front face of the insulating base member and a back-face metal body on a back face of the insulating base member, the front-face metal body being connected to at least one of the main electrodes of the semiconductor element. The insulating base member and the sealing body satisfy a relationship of Tgs≥Tgi and a relationship of αi≥αs, in which Tgi is a glass transition point of the insulating base member, αi is a linear expansion coefficient of the insulating base member, Tgs is a glass transition point of the sealing body, and αs is a linear expansion coefficient of the sealing body.
