Semiconductor device

A semiconductor device comprising:

• a semiconductor element;
• a connecting terminal that is electrically connected to the semiconductor element;
• and
• a case made of a resin, and including:
• an opening space for housing the semiconductor element;
• a frame which surrounds the opening space and in which the connecting terminal is partially embedded;
• and
• a terminal arrangement portion which protrudes from the frame towards the opening space in a protruding direction, the frame and the terminal arrangement portion of the case being made of the same material, wherein
• the connecting terminal includes an internal terminal portion that extends towards the opening space with respect to the frame, the internal terminal portion having a front surface that is electrically connected to the semiconductor element and is exposed to the opening space and a rear surface that is fixed to the terminal arrangement portion,
• the internal terminal portion includes an end portion at a side opposite to a side where the frame is located,
• the end portion has, in a direction orthogonal to the protruding direction, one and an other side portions and a central portion between the one and other side portions,
• only the central end portion among the rest of the end portion protrudes from the terminal arrangement portion and is entirely exposed to the opening space over the terminal arrangement portion, and
• each end surface of the one and other side end portions forming, together with an end surface of the terminal arrangement portion, a flat surface that is orthogonal to the front surface and the protruding direction.
