Semiconductor device

摘要

A semiconductor device includes a terminal electrode (4) and a terminal electrode placement member (21). The terminal electrode includes a substrate-fixed portion (31) secured to the circuit substrate (11) through a fastening member (36), and an external wiring connection portion (30) to which an external wiring is connected. The terminal electrode placement member includes a plurality of securing portions (122) which are secured to the circuit substrate, and a rotation suppressing portion (21) configured to suppress rotations of the terminal electrode. The rotation suppressing portion is provided with a penetration hole (121b) for penetrating the substrate-fixed portion therethrough. The rotation suppressing portion includes a pair of walls (121a) which are opposed to each other and also are positioned in opposite sides beside the terminal electrode which is inserted into the penetration hole at the substrate-fixed portion. The terminal electrode comes into contact with these walls, thereby suppressing the rotation of the terminal electrode.
