A small and thin surface-mount type optical semiconductor device having high air tightness, which can be manufactured at a reduced cost includes: a baseformed of a glass substrate; a recessformed on a first main surfaceof the base; a through holeextending from a bottom portionof the recess to a second main surfaceof the base; an inner wall conductive film formed on an inner wall surface of the through hole; a wiring patternmade of a conductive film formed around an opening of the through hole on the bottom portion of the recess so as to be connected electrically to the inner wall conductive film; an optical semiconductor elementbonded to the wiring pattern via a conductive bonding material; a terminal portionmade of a conductive film formed around an opening of the through hole on the second main surface such that it is connected electrically to the inner wall conductive film; and a metal portionbonded to the inner wall conductive film to clog the through hole.
