To provide an optical module having small number of components, a simple structure, and no optical leakage to the next channel.
A method for manufacturing an optical module comprises the steps of forming a circuit pattern 8, on the rear surface of a transparent inorganic material susbstrate 3 to be an optical transparent member, packaging a plurality of photoelectric transducers 9, 10 to the circuit pattern 8, forming a package-side electrode 6 on an upper border surface of a package 2, forming a substrate-side electrode 11 on the rear surface of the inorganic material substrate 3 corresponding to the package side electrode 6; forming a package side joining frame 72 at the periphery of the package side electrode 6 of the package 2; fixing a plurality of solder balls 73 to the substrate side electrode 12 of the inorganic material susbtrate 3 and to the periphery of the substrate side electrode 12 to be lined up, solder bonding the package-side electrode 6 and the substrate-side electrode 12, as well as bonding the inorganic material substrate 3 to the package 2.
