Abstract
A case of a semiconductor device has sidewall portions which surround sides of a metal substrate along the sides and a coating portion which covers the front surface of the metal substrate surrounded by the sidewall portions and which has through ring holes corresponding to fixing holes. Protrusions are formed on inner surfaces of the sidewall portions opposed to one another in plan view with the ring holes therebetween. The metal substrate is inserted in this way into an area surrounded by the sidewall portions of the case and is reliably fixed. Furthermore, alignment is performed with accuracy between each fixing hole of the metal substrate inserted in this way and its corresponding ring hole of the case.
