Abstract
A roofing tile for performing solar-light power generation includes a roofing tile main body set tilted on a roof, and a photovoltaic module fixed to the main body. The roofing tile main body has a recess open upward. The photovoltaic module is stored and fixed in the recess. The roofing tile main body has an eaves-side edge portion. This edge portion has a plurality of drain ditches. Each drain ditch crosses the upper portion of the eaves-side edge portion and communicates with the recess. The level of the bottom surface of each drain ditch is equal to or lower than that of the bottom surface of the recess. With this construction, rainwater that has entered the recess is discharged through the drain ditches. Rainwater is drained by running the rainwater downward on the upper surface side of the eaves-side edge portion along the tilt direction of the roofing tile.
