Abstract
Reliability of a semiconductor device is improved. Each of a plurality of terminals formed on a chip mounting surface included in a wiring substrate has a shape in which a narrow width portion is arranged between adjacent wide width portions in plan view. Moreover, a center of a tip end surface of each of a plurality of protruding electrodes formed on a semiconductor chip mounted on the wiring substrate is arranged at a position where it overlaps the narrow width portion in plan view, and the plurality of terminals and the plurality of protruding electrodes are electrically connected to each other via a solder member.
