An optical module has a housing (14) of synthetic resin, a semiconductor device (10) supported by the housing, and a spherical lens (12) held in the housing. The housing has a plurality of teeth (24) holding the spherical lens press-fitted between the teeth. Each of the teeth has a radially inner surface made up of at least three curved surfaces (30,32,34). Each of the teeth has a radially outer surface inclined such that the proximal end thereof is spread radially outwardly from the distal end thereof. The housing has a portion which surrounds the teeth and is recessed to a large depth (L), and the radially outer surface of each of the teeth has a round surface at the proximal end thereof. <IMAGE> |
