Abstract:
1. An optical-semiconductor device comprising: an optical-semiconductor element; a first electrically conductive member having a top surface whereon the optical-semiconductor element is mounted and a bottom surface that constitutes the external surface of the optical-semiconductor device; a second electrically conductive member that is separated from the first electrically conductive member and has a bottom surface that constitutes the external surface of the optical-semiconductor device; a base member having a light blocking resin and is disposed between the first electrically conductive member and the second electrically conductive member; and a sealing member having a translucent resin and covers the optical-semiconductor element, wherein the first and second electrically conductive members are formed by plating, and wherein at least one of the first and the second electrically conductive members has a bottom layer containing Au, a first intermediate layer containing Ni or Cu, a second intermediate layer containing Au, and a top layer containing Ag.
