PROBLEM TO BE SOLVED: To prevent a leakage into the roof wall of a building from a connecting section between mutual roof plates of rainwater, and to increase force resisting slipping-out from the upstanding connecting edge of the roof plate of a cap by disturbance force. SOLUTION: Each left-right impervious projecting strip 6 of the roof plate 1 is formed by folding-down to the roof plate 1 side from the upper edges of each left-right upstanding connecting edge 4. Rainwater lifting inversion spaces 26 and rainwater going-in-out openings 27 are formed among each upstanding connecting edge 4 and each impervious projecting strip 6 in a vertically arranged manner. The connecting structure is constituted in such a manner that parts of rainwater on the roof plate 1 are blown up along the upstanding connecting edges 4 when they are blown into the upstanding connecting edge 4 sides by a wind, are lifted up to the rainwater lifting inversion spaces 26 from the rainwater going-in-out openings 27 and are inverted and drop and gradually drop onto the roof plate 1 from the openings 27.
