An optical communication module

It is expected to provide an optical communication module that is not limited, a conductive plate such as a lead frame in response to the reduction in size of the photoelectric conversion device such as a laser diode or a photodiode thinner form, and causes no decrease in size of a lens , A laser diode 20 is connected to a conductive plate at the upper surface of a transparent light transmission plate 70 and fixed thereto. The light transmission plate 70 is connected to a conductive plate 30 on the upper surface of a transparent base 10 and fixed thereto. A first lens 14 and second lens 15 are each integrally formed on the top surface and the bottom surface of the base 10 degrees. The laser diode 20 performs transmission of optical signals through the gap of a conductive plate 60, the transparent light transmission card 70, the opening portion of a conductive plate 65, the opening portion 31 of a conductive plate 30, the first lens 14, the transparent base 10 and the second lens 15 through.
