Abstract
Disclosed is a wiring substrate whose orientation can be easily recognized and which can prevent occurrence of a failure which would otherwise occur after a semiconductor device is mounted on the wiring substrate, or after an electronic component composed of the wiring substrate and the semiconductor device mounted thereon is mounted on a base substrate or the like. The wiring substrate includes a base substrate, and a metallic member disposed on a first face of the base substrate. The metallic member has a shape which is plane symmetric with respect to a plane which extends through a center of the first face and is perpendicular to the first face. A recess is formed, as a partial dent, on one of outer surfaces of the metallic member.
