Abstract

A case and a semiconductor device including the case are provided for solving the following issues: when fixing a lid body to a case body by an adhesive, a process of attaching the lid body to the case body by applying the adhesive and curing the adhesive by heating is necessary, which requires much labor; also, when fixing the lid body to the case body by an engaging claw, it still requires much labor due to forming the engaging claw. The case includes a first member and a second member that is engaged with the first member to form an accommodation space inside the case, and the first member has a protruding portion extending from the first member side toward the second member side and having an end portion crushed from the opposite side of the first member to fix the second member to the first member.
