ABSTRACT:
A semiconductor element module of the invention comprises a sleeve, a stem, a semiconductor light-emitting or light-receiving element, and a converging lens. In the sleeve, a fitting portion in which a ferrule for positioning an optical fiber is to be fitted is formed from its one open end toward the interior, an element housing portion coaxial with the fitting portion is formed from the other open end toward the interior, and a lens holding portion is formed to connect the fitting portion and the element housing portion. The stem is fixed to the sleeve at the other open end. The semiconductor light-emitting or light-receiving element is fixed on a surface of the stem on the element housing portion side. The converging lens is housed in the element housing portion and fixed to the sleeve, and optically couples an end face of the optical fiber to the light-emitting end face of the semiconductor light-emitting element or the light-receiving end face of the semiconductor light-receiving element. The material constituting the sleeve includes a metal having a thermal expansion coefficient close to that of a material constituting the converging lens.
