Patent ID: 8267597

Claim:
An optical module comprising: an optical device mounting board including a first surface, a second surface on a reverse side of the first surface, and a first light transparent part allowing an emitted light traveling in a direction from the first surface to the second surface and a received light traveling in a direction from the second surface to the first surface to pass through the first transparent part; an optical device mounted on the first surface, which is a light emitting device emitting the emitted light or a light receiving device receiving the received light, and of which a wiring terminal is formed on a same surface as a light emission or light receiving side, wherein the light emission or light receiving side of the optical device faces the first surface of the mounting board; a first terminal mounted on a surface except the first surface of the optical device mounting board; a wiring connecting a second terminal of a component mounted on the first surface including the optical device with the first terminal; and a transmission medium connector connecting a light transmission medium transmitting the emitted light traveling in a direction from the second surface to an outside of the optical module or the received light traveling in a direction from the outside to the second surface.
