Abstract: A solar cell module includes a light-receiving surface-side protective member, a rear surface-side protective member, solar cell elements, and an encapsulating layer that encapsulates the solar cell elements between the light-receiving surface-side protective member and the rear surface-side protective member. The light-receiving surface-side protective member has a plurality of fine recess portions and a plurality of fine protrusion portions on at least a solar cell element side surface, busbar electrodes are provided to the solar cell elements on at least a light-receiving surface-side surface. The encapsulating layer has a light-receiving surface side-encapsulating layer having an effective thickness of 0.01 mm to less than 0.25 mm and a rear surface-side encapsulating layer, and the solar cell elements are encapsulated between the light-receiving surface side-encapsulating layer and the rear surface-side encapsulating layer. A solar cell-encapsulating material configuring the light-receiving surface side-encapsulating layer has a defined elastic modulus at 23° C.
