摘要： An optical module includes a circuit board, a photoelectric conversion element mounted on the circuit board, an optical connector for optically connecting the photoelectric conversion element and an optical fiber, a semiconductor circuit element mounted on the circuit board and electrically connected to the photoelectric conversion element, a pressing member for pressing and fixing the optical connector to the circuit board, and a supporting member for supporting the pressing member. The supporting member includes a heat-absorbing surface and a heat-dissipating surface. The heat-absorbing surface is thermally connected to the semiconductor circuit element. The heat-dissipating surface dissipates heat of the semiconductor circuit element to be absorbed through the heat-absorbing surface.

摘要： There is provided a photoelectric conversion module that can be mounted two-dimensionally over a device board in a high-density, low-height manner and cooled efficiently with an easy-to-install collective-type radiator. In the photoelectric conversion module mounted over the device board, an optical connector is attached to that surface of an optical subassembly facing the device board. An electric connector has at least two sides thereof opened so that the optical transmission medium is threaded therethrough and extended through at least two facing sides of the optical subassembly. The optical transmission medium is thus extended between the optical subassembly and the device board in a vertically stacked manner.
