<p>Provided is a terminal box for a solar cell module having improved heat radiation. A box main body (20) of a terminal box (10) accommodates a plurality of terminal plates (50), and a diode (60) connected so as to be energizable to the terminal plates (50). The diode (60) has a heat-radiating surface (65) disposed facing a metallic frame (80) attached along an external periphery (95) of a solar cell module (90). When the diode (60) generates heat, the heat is released from the heat-radiating surface (65) to the frame (80).</p>
