Abstract
An optical semiconductor device is disclosed that includes an optical element mounted on a substrate and a window lid sealing the optical element in a space on the substrate. The window lid includes a frame member and a glass plate member. The frame member, formed by performing drawing on a metal plate, includes a top plate part having an opening window, a peripheral side plate part connected to the peripheral edge of the top plate part so as to surround a space thereon, and a flange part extending outward from the peripheral edge of the peripheral side plate part on the side opposite from the top plate part. The glass plate member, contained in the space formed by the top plate part and the peripheral side plate part, is welded to the substrate-side surface of the top plate part and the internal surface of the peripheral side plate part.
