PROBLEM TO BE SOLVED: To provide a laser diode module for optical communications which is equipped with a micro thermoelectric cooling element capable of manufacturing in a low cost module and mounting on a small OSA. SOLUTION: The laser diode module for optical communications is composed of a housing 30 having a side wall, a heat sink 32 located on an upper surface of the housing, a superlattice micro cooler 40 placed on an upper surface of the heat sink, a laser diode 35 which is positioned on an upper surface of the superlattice micro cooler and emits a laser beam, a photodiode 37 which converts light emitted from the laser diode to an electric current, and a light collecting element 38 which is located on the upper surface of the heat sink and collects the laser beam emitted from the laser diode.
