PROBLEM TO BE SOLVED: To provide a joint box for photovoltaic power generation which is made compact, by allowing assembly of a switch, a backflow prevention diode, and the like, while saving the space.SOLUTION: A heat dissipation plate 4 wide enough to cover the apparatus attachment region entirely is placed tightly on the inner back plate 5a of a joint box 10, a diode module 2 is brought into tight contact with the heat dissipation plate 4, and a switch 1 is fixed onto the heat dissipation plate 4 via a switch mount 11. Back part of the switch mount 11 can be used as a heat dissipation space, a housing section is provided so that a portion of the diode module 2 overlaps the back of the switch 1, and the output terminal 1a of the switch 1 and the input terminal 20a of the diode module 2 are arranged closely to each other. |
