As described above, according to the structure of the present invention, in the solar cell module, the sealing member for sealing the peripheral portion of the solar cell module body is the receiving frame member (joint receiving frame member). And the pressing frame member (joint pressing frame member), respectively, are fixed by tightly sandwiching the solar cell module from above and below, respectively.
Since the sealing member is made of an elastic body, the projecting ridges provided along the peripheral edge of the sealing member serve as a holding frame member (joining holding frame member) and a receiving frame member (joining receiving frame member). Since it is compressed and deformed by being pressed and sandwiched, it can be brought into close contact with the receiving frame member and the pressing frame member, and it is possible to prevent rainwater from leaking from the upper side at the joint portion between the sealing member and the mounting member.

Further, the auxiliary mounting member according to claim 6 is arranged in a direction orthogonal to the receiving frame member and the pressing frame member,
If the receiving frame member, the end of the pressing frame member, and the end of the solar cell module on the side where the receiving frame member and the pressing frame member are not provided are closed, the receiving frame member and the pressing frame member are provided. Rainwater intrusion from the side that is not protected can also be suppressed. Further, if the joint mounting member according to claim 7 is arranged in a joint between the solar cell module and the adjacent solar cell module, the joint being orthogonal to the receiving frame member and the pressing frame member, the joint is formed. Is blocked from the upper side, so that rainwater can be prevented from entering from the joint portion. Furthermore, if the receiving frame member is provided with a rain gutter part for allowing rainwater to flow down, even if rainwater leaks from the joint between the sealing member and the receiving frame member or the pressing frame member, the receiving frame member can be removed. It is possible to prevent it from reaching the mounting portion mounted on the roof surface by the fixing tool and further reaching the roof surface directly below the fixed solar cell module. Therefore, the roofing material can be omitted at the installation location of the solar cell module.
