ABSTRACT:
An optical communication module in which an incident or emergent end of an optical fiber can be easily and precisely aligned with a light-emitting element or a light-receiving element. The optical communication module includes a base block that has a first surface and a second surface located opposite to the first surface, a microelement such as a light emitting element or a light-receiving element that contacts the first surface. The second surface includes an optical-fiber guide hole, and the microelement contacting the first surface and an optical-fiber received in the optical-fiber guide hole are separated by an intervening portion of the base block.
