As shown in FIG. 1, a roof tile 1 for a solar cell module is, for example, a thick slate obtained by press-molding cement mortar, and has three peaks 3a, 3b, 3c and three valleys 5a, 5b, 5c are parallel and alternate with each other. Each peak 3 is formed at the same height, and each valley 5 is formed at the same depth, and each has a rectangular cross-sectional shape.

As shown in FIG. 2, the roof tile body 4 accommodates a solar cell module 2 described later in a recess 6 (described later). The solar cell module 2 is bonded to the recess 6 with an adhesive. The tile body 4 on which the solar cell module 2 is mounted as described above is laid in a state of being aligned vertically and horizontally along the inclined roof of the building. At this time, each tile body 4 is laid on the roof so that each mountain portion 3 and each valley portion 5 of the tile body 4 extend from the ridge side of the roof to the eaves side along the inclination direction, and the tile body 4 is vertically moved along the inclination direction Each valley portion 5 of the tile body 4 arranged side by side functions as a continuous drain groove.

On the upper surface 1a of the tile main body 2, for example, an apparently rectangular recess 6 extending over three peaks 3a, 3b and 3c is provided.
Is provided. The recess 6 is formed slightly deeper than the thickness of the solar cell module 2, and has a size that matches the dimensions of the solar cell module 6. Further, the concave portion 6 has a bottom portion 6a with which the back surface of the solar cell module 2 is in contact, and a locking portion 6b with which the four ends of the solar cell module 2 are in contact with each other and locked.
The bottom 6 a is formed shallower than each valley 5 of the tile body 4. With such a configuration, the rainwater flowing in each valley 5 of the tile main body 4 flows on the back side of the solar cell module 2 at the recess 6.
