Abstract:
1. An optical module comprising: a mounted member that includes an inserted portion; a surface optical device that includes a positioning portion that is provided in the mounted member, the positioning portion having a pair of inclined surfaces and a vertical surface, the inclined surfaces positioning X and Y directions of an optical axis of an optical transmission member and the vertical surface positioning a Z direction (optical axis direction) of the optical axis of the optical transmission member so that the optical transmission member is optically coupled to the surface optical device and a gap exists between the optical transmission member and an optical surface of the surface optical device; the insertion portion having a convex portion and a base portion, the insertion portion further having a bottom surface that positions a Z direction (optical axis direction) of the optical axis of the surface optical device, a vertical wall surface that positions an X direction of the optical axis of the surface optical device, and a horizontal wall surface that positions that Y direction of the optical axis of the surface optical device; the inserted portion being a dent, the dent having a first dent portion into which the convex portion of the insertion portion is inserted, and a second dent portion into which the base portion of the insertion portion is inserted.
