PROBLEM TO BE SOLVED: To provide a snow guard function and protect wiring structure at a terminal takeoff part and at the back of a roof board by providing at least one part of a roof board body with a protruding part protruded on the light receiving face side and recessed on the light nonreceiving side, and enclosing the terminal takeoff part in the protruding part. SOLUTION: A solar battery integrated roof board 61 is constituted to seal an amorphous silicon photovoltaic element on a galvaliuns steel plate with sealing material. A protruding part 41 is provided directly above an eaves side engaging part over a girder direction. After forming engaging parts 42, 43 and the protruding part 41, a power takeoff electric wire 45 is taken out of a hole 44 opened in the back face of the steel plate at the longitudinal end of the protruding part 41. The electric wire 45 can be made shortest by thus tanking it out of the roof board end part. The roof board 61 can therefore have structure having snow guard function and protecting wiring members existing at a terminal takeoff part and on the back side of the roof board.
