ABSTRACT:
An optical waveguide module includes a wiring board, and a light-receiving element and optical waveguide substrate that are positioned on both sides of this wiring board. The wiring board includes a base member having transparency to light of the wavelength that can be received by the light-receiving element; surface electrical wiring on the surface of the base member, and filter film on the rear surface of the base member for passing only light of the wavelength that can be received by the light-receiving element and for reflecting light of other wavelengths. An aperture larger than the core of the optical waveguide is formed in the surface electrical wiring. The light-receiving element (9) is flip-chip mounted on surface electrical wiring (4) using bumps (11), and the light-receiving region (10) of the light-receiving element (9) is arranged to face the wiring board (7).
