Patent abstract
An optical device comprises a copper plate having an opening; a flexible board placed below the copper plate; a light receiving element substrate placed below the copper plate and mounted on a wiring pattern of the flexible board via bumps; a light emitting element and a light receiving element both provided at the principal surface of the light receiving element substrate; and a supporting frame supporting the flexile board in a downwardly posture. The supporting frame fixes the flexible board and the copper plate. Therefore, a thin optical device can be realized without employing a resin mold structure.
