Abstract

PROBLEM TO BE SOLVED: To reliably drain flooding by installing a solar battery in a recessed part arranged in an obverse side central part of a flat roof tile, and arranging through holes to communicate with the reverse side in the vicinity of the lower side peripheral edge orthogonal to the flow pitch direction of the flat roof tile of the recessed part. SOLUTION: A recessed part 13 is arranged in a central part of the peripheral edge 12 becoming a superposing object part by being superposed at thatching time of a surface of a flat roof tile 11, and through holes 14 to communicate with the reverse side are juxtaposed in the vicinity of the lower side peripheral edge 13a orthogonal to the slope gradient direction of the flat roof tile of this recessed part 13. A solar battery 15 to which a connecting cord 15a is connected is installed in the recessed part 13 of this flat roof tile 11, and a roofing tile 10 having a solar battery is formed. This roofing tile 10 having a solar battery is thatched on a sheathing roof board on a roof. Next, when rainwater infiltrates into the recessed part 13 of the roofing tile 10, the rainwater is drained to the upper side peripheral edge of a superposing part of a lower side roofing tile 10 by the through holes 14 of an inside end part of the lower side peripheral edge 13a under a slope gradient. Therefore, the occurrence of a hindrance to performance of the solar battery by wetting by water and the degradational promotion of a surface of the tile can be prevented.
