Abstract
An optical module includes an optical waveguide including a waveguide core through which light propagates and a clad configured to trap the light in the waveguide core, and a circuit board on which a surface-type optical element is mounted. The optical waveguide further includes a reflective surface from which an end face of the waveguide core is exposed, the reflective surface being provided on an inclined face at one end face of the optical waveguide core in an extending direction of the waveguide core, and an element mount opening provided in the clad such as to be opposite from the reflective surface, the element mount opening having a size such as to contain the optical element. The optical waveguide is mounted on the circuit board while the optical element is contained in the element mount opening and is aligned with the reflective surface of the optical waveguide.
