PROBLEM TO BE SOLVED: To enhance electric power generation (cost effectiveness) per solar battery cell area, in a structure for incorporating a plurality of solar battery cells into a building material made of a corrugated plate or a folded plate, on which projections and depressions appear in a constant period.SOLUTION: In a solar battery-integrated building material, a plurality of solar battery cells are incorporated into a base material where projections and depressions, elongated in a constant direction, are repeatedly formed. The solar battery cell is arranged in each projecting area including the top of the projection, and the adjacent solar battery cells are electrically connected together in a depressed area between the projecting areas. |
