Abstract
A wiring substrate includes: a substrate body made of ceramic and having a front surface and a rear surface, each having a rectangular shape in a plan view, a plurality of rear surface electrodes formed on the rear surface of the substrate body, a frame-shaped conductive portion provided on the front surface side of the substrate body, and a via conductor penetrating the substrate body and establishing electric connection between the plurality of rear surface electrodes and the frame-shaped conductive portion. A part of the rear surface is exposed between the plurality of rear surface electrodes and each side of the rear surface of the substrate body. On the rear surface of the substrate body, at least one projecting wiring is formed between each of the plurality of rear surface electrodes and each of a corresponding pair of the sides that intersect with each other.
