[0082] A first preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 6 . The terminal box for a solar battery module according to this embodiment is mounted or can be mounted on one side (preferably the bottom side) of a solar battery module (not shown) having many solar battery cells, so The battery cells are arranged in series on the outer surface of the solar cell module. The terminal box is provided with: a box main body 10 , a plurality of terminal boards 30 roughly juxtaposed in the box main body 10 , and one or more rectifying device units 50 respectively bridged between adjacent terminal boards 30 . In the following description, with respect to the front-rear direction FBD, the upper side in FIG. 1 (ie, the side opposite to the lead-out side of the cable 80 described later) is referred to as the front side.
[0083] The box main body 10 is made of, for example, a synthetic resin material, is substantially box-shaped, and ha...

[0110] Figure 8 shows a second preferred embodiment of the invention. The second embodiment differs from the first embodiment in that a plurality of bypass diodes 52 are collectively held by one metal clip 53 .
[0111] Specifically, the clip 53 in the second embodiment has a shape that is broadened substantially in the width direction WD like the clip 53 in the first embodiment so as to be able to collectively hold the clips in the width direction WD or substantially side by side. A plurality (three in the illustrated case) of bypass diodes 52 and includes a pair of wide support plates 56 . The upper surface area of the substrate 11 behind the middle portion (preferably substantially the center portion) with respect to the front-back direction FBD, that is, the area behind the disposition position of the terminal board 30 serves as a mounting surface on which the clip 53 is placed. One or more engaged portions 19 protrude at one or more (for example two) positions on (pref...

[0115] 9 to 11 show a third preferred embodiment of the present invention. The third embodiment differs from the first and second embodiments in that a pair of divided bodies 57 are used corresponding to the heat radiation elements of the present invention.
[0116] A pair of divided bodies 57 are formed in a block shape from metal (preferably aluminum) or a material having good heat transfer characteristics or thermal conductivity, and by combining the two divided bodies 57, the bypass diode 52 can be firmly held in the thickness direction TD. between the facing surfaces of the two split bodies 57 . One split body 57A of the two split bodies 57 may at least partially remain in substantially contact with the first (upper) surface of the bypass diode 52, and the other split body 57B may at least partially remain in substantially contact with the second substantially contact surface of the bypass diode 52. The opposite (lower) surface, as shown in Figure 10.
