ABSTRACT:
An optical semiconductor element includes a light-emitting element, a light-receiving element that is placed opposite to the light-emitting element, and two lead frames on which the light-emitting element and the light-receiving element are respectively die bonded. Shield plates are bent respectively toward the light-emitting element or the light-receiving element at a predetermined angle with respect to the surface of a die bonding region on the periphery of the die bonding region of the lead frames.
