ABSTRACT:
A light emitting element and a light receiving element are mounted on respective lead frames. The light emitting element and one lead frame, and the light receiving element and the other lead frame are covered with respective light transmissive primary moldings. A light shielding secondary molding is formed to unify the primary molding on the light emission side and the primary molding on the light reception side. The respective lead frames extend outward from the respective primary moldings and bent within and extend outward from the secondary molding. A bottom surface of the secondary molding is aligned with respective lower surfaces of the lead frames. A precision in positioning of a photointerrupter with respect to a substrate can be increased.
