Abstract
A shield case is formed by bending one sheet of a magnetic metal plate that is generally in a T-character form, which has a top plate, two side plates sandwiching the top plate, and a back plate extending from a rear edge of the top plate and sandwiched between the side plates. A semiconductor optical device is placed between the side plates, and elastically held at its side surfaces by clamp pieces formed in the side plates. By inwardly bending the back plate to a position in parallel to the top plate, the semiconductor optical device at its back and bottom surfaces is shielded. The side surfaces and light-receiving/light-emitting surface of the semiconductor optical device are respectively shielded by the side plates and the top plate.
