Abstract
An optical semiconductor device includes a semiconductor substrate provided with a light-receiving element, a frame-shaped rib member, and a transparent substrate in this order, and an adhesive layer bonding the rib member and the semiconductor substrate to each other. The rib member and the adhesive layer are provided so as to surround the light-receiving element. In the optical semiconductor device, the adhesive layer protrudes outward from an outer peripheral surface of the rib member when the rib member and the adhesive layer are viewed from a transparent substrate side. A coverage ratio of the adhesive layer on an inner peripheral surface of the rib member is 30% or less.
