A case (6) surrounds a semiconductor chip (5). A case electrode (7) is attached to an upper face of the case (6). A wire (8) is connected to the semiconductor chip (5) and the case electrode (7). A first holding portion (10) presses down the case electrode (7) on the upper face of the case (6) outside a joint portion where the wire (8) is bonded to the case electrode (7). A second holding portion (11) presses down the case electrode (7) on the upper face of the case (6) inside the joint portion. A recess (12) is formed on the upper face of the case (6). The case electrode (7) is bent such as to fit into the recess (12). The second holding portion (11) is disposed inside the recess (12).
