PROBLEM TO BE SOLVED: To provide an LD heat radiation structure capable of radiating the heat of the surface part of the cylindrical metal package of a laser diode to an exterior part covering the laser diode. SOLUTION: A heat radiation member 2a is provided so as to be in contact with the cylindrical metal package 12 of the laser diode 1, and the heat of the cylindrical metal package 12 of the laser diode 1 is radiated through the heat radiation member 2a to the exterior part 3 covering the laser diode.
