PROBLEM TO BE SOLVED: To provide a corrugated tile which enhances the beauty of the corrugated tile in which a ridge part is provided in a central part of a tile body, structurally allows a worker for constructing or repairing a roof to land easily on the corrugated tile, and has an excellent additional function with which a conventional technology is not equipped. SOLUTION: The first and second ridge parts 2 and 6 having an approximately half-split cylinder shape are formed in parallel at a prescribed interval near the central part of the tile body 1 serving as a main body of the corrugated tile M, in such a tapered shape as to be made wider from a butt part 3 of the corrugated tile M to a head part 4 thereof. Thus, in the ridge parts 2 and 6, an arc-shaped surface of a top part to the head part 4 is made larger than that of a top part to the butt part 3; and the expanded width of a valley part 17, which is formed between the ridge parts 2 and 6, is made narrower toward the head part 4. At the landing of the worker, a force of sliding on the corrugated tile M in the direction of edge of eaves is applied to side surfaces of the ridge parts 2 and 6, so that downward stress can be decentralized so as to make sliding hard. The corrugated tile M having such a structure also exerts a snow guard effect. COPYRIGHT: (C)2004,JPO
