A terminal box device has a body unit and a cover unit. The cover unit has a cover member, terminal members and bypassing diodes. Cables lead into the cover member, and the cover member includes a filler which covers the end of the panel cables, part of the terminal members, and the bypassing diodes. The body unit has a casing including wiring holes, terminals, a waterproof seal installed on a groove formed along an upper surface of a peripheral wall of the casing, and waterproof walls surrounding each wiring hole. The terminal members and the terminals are electrically connected with each other by installing the cover unit on the body unit. The waterproof seal and the waterproof walls prevent water from penetrating into the body unit.
