摘要

Holes (131) are formed in a major surface of a hybrid IC insulating substrate (13) mounting an optical semiconductor element, and terminal pins (12) of a package (11) are connected and fixed to the substrate while head portions of the terminal pins are inserted in the corresponding holes. Since the terminal pins do not protrude outside the major surface of the insulating substrate, a space therefor can be omitted, and the terminal pins are directly connected to the insulating substrate without being separated from each other. Furthermore, since the head portions of the terminal pins are inserted in the corresponding holes of the insulating substrate, they can be automatically aligned. In case that each hole has a tapered inner surface, insertion of the terminal pins can be further facilitated.
