Patent ID: 6915049

Claim:
A method of manufacturing an optical module comprising: mounting an optical device on a substrate in a manner that an optical part of the optical device faces an aperture formed in the substrate without which an optical path is not secured; aligning an optical waveguide with its end surface facing the optical part through the aperture, the optical waveguide being provided with a fixing part surrounding an outside surface of an end portion of the optical waveguide except the end surface of the optical waveguide facing the optical part, the fixing part provided with an aligning guide projecting from a surface of the fixing part in an axial direction of the optical waveguide; and providing a light-transmissive resin in the aperture, wherein the aligning includes positioning the surface of the fixing part from which the aligning guide projects to be opposed to the substrate and attaching the guide to a guide receiving section, a position of which is determined relatively with the optical device.
