PROBLEM TO BE SOLVED: To provide an art in a semiconductor device, which is capable of reducing man hour required for an attach/detach work of a fastening jig when bonding a base plate and a case by an adhesive, and capable of securing the base plate and the case with high fastening power. ! SOLUTION: A semiconductor device comprises: a base plate 1 on which an attachment part having a screw part 1b is formed and a semiconductor element is arranged; a bush 3 capable of being screwed with the attachment part of the base plate 1; and a case 2 in which an insertion hole 2b capable of inserting the bush 3 is formed. Further in the semiconductor device, by screwing the bush 3 to the attachment part of the base plate 1 in a state where the case 2 is placed on the base plate 1, the base plate 1 and the case 2 are secured. !
