TERMINAL BOX FOR SOLAR CELL MODULE

Provided are a heat dissipating plate (9A, 9B, 9C) with good thermal conductivity extending over the body bottom surface of a box body (20A), and four terminal strips (1A, 1B, 1C, 1D) with good thermal conductivity to which an output lead wire extending from a solar cell module (100) and a module coupling cable (16a, 16b) extending to outside is connected. A sealed portion (8a) of a diode (8A, 8B, 8C) provided for bypass in reverse loading is interposed between the heat dissipating plate (9A, 9B, 9C) and the terminal strips (1A, 1B, 1C, 1D). The heat can be dissipated efficiently from the lower surface of the sealed portion (8a) through the heat dissipating plate (9A, 9B, 9C) to the solar cell module (100). The heat can also be dissipated efficiently from the upper surface of the sealed portion (8a) through the terminal strips (1A, 1B, 1C, 1D) to the output lead wire and the module coupling cable (16a, 16b).
