Abstract: To obtain a reinforcing frame capable of securing sufficient reinforcing strength and adhesive strength while suppressing a manufacturing cost by omitting a rim-like frame. A reinforcing frame is adhered to a rear surface, which is a non-light receiving surface of a solar battery panel, and includes a cylindrical portion that has a cylindrical shape along a longitudinal direction of the reinforcing frame and on which an adhesive surface for adhering to the solar battery panel is formed, and protruding portions that protrude from end portions along a longitudinal direction of the adhesive surface and that are substantially parallel to the adhesive surface.

Abstract: A solar cell module includes a solar cell panel including a light receiving surface, a rail-like holding member joined to a rear surface on the opposite side of the light receiving surface in the solar cell panel, the holding member reinforcing and holding the solar cell panel, an assisting member fixed to an end in a longitudinal direction of the holding member within the holding member, the assisting member assisting the holding of the solar cell panel by the holding member, and a screw that fixes the assisting member to the holding member. The assisting member has a bent shape bent in a direction opposed to the light receiving surface from a portion erected to the light receiving surface side through an edge of the solar panel from a position on the rear surface side fixed to the holding member by the fixing member.
