A plurality of the first draining members 141 are arranged side by side in the width direction orthogonal to the inclination direction on the roof surface, and adjacent side surfaces are bonded to each other. The first draining member 141 has a role of supporting a second draining member 142 to be described later and fixing it to the roof surface.

The first draining member 141 has a bottom surface portion 141A, a first inclined surface portion 141B, and a mounting surface portion 141C.
The bottom surface portion 141A extends along the base material 5 and is fixed to the base material 5 with screws. The ridge-side end portion of the bottom surface portion 141 </ b> A is disposed on the lower surface of the eaves-side end portion of the waterproof tape 24 disposed on the lower surface of the gantry 20 of the solar panel 2.

The first inclined surface portion 141B is formed to be thick so as to extend obliquely upward from the ridge side end portion of the bottom surface portion 141A toward the eaves side. A concave portion 141D that is recessed toward the ridge side is formed at the eaves side end portion of the first inclined surface portion 141B. A first engagement piece 142B of a second draining member 142 to be described later is engaged with the recess 141D.
