Patent ID: 7568846

Claim:
An optical reception and transmission module comprising: an optical waveguide film that guides light; an optical transmission unit comprising a light emitting element, a first optical path converting part that guides light, and that comprises, at a first end surface thereof in an optical waveguide direction, a mirror surface that bends light which is emitted from the light emitting element and which enters the first optical path converting part from an incident end surface thereof, and a first holding member that holds the light emitting element and the first optical path converting part so that the light emitted from the light emitting element is coupled to the incident end surface of the first optical path converting part; an optical reception unit comprising a light receiving element, a second optical path converting part that guides light and comprises, at a first end surface thereof in the optical waveguide direction, a mirror surface that bends the guided light, and a second holding member that holds the light receiving element and the second optical path converting part so that the light bent by the mirror surface of the second optical path converting part is received by the light receiving element; a first supporting member comprising a first hole portion into which a first end portion of the optical waveguide film is inserted, and which supports the first end portion of the optical waveguide film inserted into the first hole portion so that a first end surface of the optical waveguide film in the optical waveguide direction and a second end surface of the first optical path converting part in the optical waveguide direction are optically coupled; and a second supporting member comprising a second hole portion into which a second end portion of the optical waveguide film is inserted, and which supports the second end portion of the optical waveguide film inserted into the second hole portion so that a second end surface of the optical waveguide film in the optical waveguide direction and a second end surface of the second optical path converting part in the optical waveguide direction are optically coupled, wherein at least one of the first supporting member or the second supporting member is formed by layering a transparent second member on a first member comprising a recessed portion.
