ABSTRACT:
In an optical transmission module, guide pins have formed thinned parts and/or pass-through parts, and fixing grooves formed in a base to receive the guide pins are shaped to satisfy predetermined conditions, so as to alleviate heat conduction from guide pins to an optical connector and to firmly fix the guide pins in the grooves with an adhesive without causing the extrusion of the adhesive. Thus, the optical connector can be brought into optical alignment with the optical transmission module without being excessively heated through the guide pins, and the production yield of the optical transmission module can be improved.
