Claim:
1. A semiconductor device, comprising: power semiconductor elements; an insulating circuit substrate on which the power semiconductor elements are placed; a printed substrate, electrically connected to the power semiconductor elements, which has a control circuit; a case comprising a case sidewall and a case bottom portion and having control terminal insertion holes in the case bottom portion; and control terminals which electrically connect the printed substrate and an exterior of the semiconductor device, wherein the printed substrate is disposed on a level different from that of the insulating circuit substrate and the case bottom portion, the control terminals, having a linear shape, are inserted in the control terminal insertion holes and through holes of the printed substrate, a number of the control terminal insertion holes is larger than a number of the control terminals, the control terminal insertion holes are arranged at equal pitches on one side of the case bottom portion and extend across a central portion of the case bottom portion on the one side, and the case sidewall includes a first portion and a second portion, the first portion being closer to the control terminal insertion holes than the second portion, and being thinner than the second portion.
