The present invention provides an optical communication module capable of being made compact by narrowing the distance between photoelectric devices and the distance between lenses even if it is equipped with a plurality of photoelectric devices. Since the base 10, the receiving lens face 15, the transmitting lens face 16, the pillar section 17, etc. of an OSA 1 are integrally molded using a translucent synthetic resin, the distance between the receiving lens face 15 and the transmitting lens face 16 can be made short, and the OSA 1 can be made compact. Furthermore, since the transmitting lens face 16 is provided at the protruded end of the pillar section 17 protruded from the base 10 and the peripheral face of the pillar section 17 between the receiving lens face 15 and the transmitting lens face 16 is formed into a flat face 17a, light can be reflected by using the flat face 17a as a boundary, whereby light leakage from the transmission side to the reception side and from the reception side to the transmission side can be prevented. |
