Abstract
The present invention is directed to provide a method of manufacturing an optical module in which optical devices are optically aligned with high precision regardless of elastic return of bonding bumps. The invention provides a method of manufacturing an optical module including the steps of forming bumps for bonding made of metal on a substrate, and bonding a second optical device on the bonding bumps by applying a load so that the bumps for bonding are deformed only by a predetermined amount from a position where a first optical device and the second optical device are optically coupled most efficiently and, after that, releasing the load.
