Patent ID: 7311451

Claim:
A method of manufacturing an optical communication module comprising a mold tool, in which a lead frame including a ferrule and an optical communication facility section both mounted thereon is placed, and a moving part that can be stopped at a given position relative to said mold tool and can press said ferrule so as to position a distal end of said ferrule at a proper location within said mold tool, said mold tool comprising an upper mold tool and a lower mold tool capable of being opened and closed, said moving part having a first inclined surface, said upper mold tool having a second inclined surface to fit said first inclined surface, and said second inclined surface being capably of pressing said first inclined surface in conjunction with closing operation of said upper mold tool, thereby causing said moving part to advance toward the ferrule side, the method comprising: placing a the lead frame in the mold, said lead frame provided with the ferrule and the optical communication facility section both mounted thereon; pressing said ferrule by the moving part that is moved in conjunction with closing operation of the upper mold tool and positioning the distal end of said ferrule at a proper location within said mold while absorbing a displacement and a reactive force of the lead frame by an elastic member in the lead frame; and filling a resin into said mold such that a catching portion for coupling to a connector is formed at a proper position relative to the distal end of said ferrule.
