Abstract:
1. An optical module, comprising: a circuit board having a mount surface; a photoelectric conversion element mounted on the mount surface of the circuit board; an optical coupling member for holding an optical fiber and optically coupling the optical fiber and the photoelectric conversion element; a semiconductor circuit element mounted on the mount surface of the circuit board and electrically connected to the photoelectric conversion element; and a plate-shaped supporting substrate arranged to sandwich the optical coupling member between the supporting substrate and the circuit board, wherein an electrically conductive metal foil which extends in a thickness direction of the supporting substrate is provided integrally with a side surface of the supporting substrate, and the metal foil is connected at one end thereof to an electrode provided on a non-mount surface of the circuit board; and wherein the supporting substrate is formed by dicing a rod-shaped base material made of an insulation provided with an electrically conductive metal foil along a center axis at a cross section which is orthogonal to the center axis together with the metal foil.
