An optical module includes a mounted member, a surface optical device and a positioning portion. The mounted member includes an inserted portion. The surface optical device includes a substrate, an optical axis, and an insertion portion. The optical axis is provided in a direction perpendicular to the substrate. The insertion portion has a step surface that is inserted into the inserted portion of the mounted member in a direction perpendicular to the optical axis so as to position the optical axis. The positioning portion is provided in the mounted member and positions an optical transmission member so that the optical transmission member is optically coupled to the surface optical device.
