To provide a roof tile reinforced structure by which the roof tile with a frame support tool can bear even too much weight.

In this roof tile consisting of Japanese tiles, the frame support tool 8 is inserted into between roof tiles T and T1 located back and forth in flow direction Y of the roof R to fix a base end 8a on roofed face F of the back roof tile T1, equipped with a fixing means 10 of a solar panel mounting frame on its upper end, tip side of which is installed in top rearward the front roof tile T. In between the front roof tile T and its roofed face F, there is a space in length from forward end of a bar M mounted on the front roof tile T supporting its rear end to the vicinity of rear end on a roof tile T0 in front of the roof tile T, and within a width ranging throughout its coved portion of the roof tile T. On this space, a flexible and buffered reinforcing material 11 is loaded, top face of which is formed as a curved shape fitted in reverse face of the coved portion, while its compression-deformed state matches the space shape tilting so as to be along the gradient produced when roof tiles T0, T, T1, ... are roofed.
