Abstract:
1. An optical module comprising: a case including an accommodation portion; a plurality of optical elements accommodated in and fixed to the accommodation portion of the case, wherein the optical elements have optical axis centers; a plurality of optical waveguide cores respectively formed at positions corresponding to planar positions of the optical axis centers; a clad layer surrounding the optical waveguide cores, wherein the clad layer and the optical waveguide cores form an optical waveguide; a wiring substrate including a wiring pattern to which electrode terminals of the optical elements are connected, wherein the optical waveguide is stacked on the wiring substrate, and the case is mounted on the wiring substrate on which the optical waveguide has been stacked; and an optical path changing unit formed at a position corresponding to the planar positions of the optical axis centers, wherein the optical path changing unit faces the optical waveguide at a predetermined angle; wherein the optical elements are accommodated in the accommodation portion with adjacent ones of the optical elements in contact with each other.
