A solar battery module includes: a front face protective sheet at a first side; a sheet-shaped solar battery cell disposed at a second side, the second side being an opposite side from the first side with respect to the front face protective sheet; a backing sheet disposed at the second side with respect to the solar battery cell; and an encapsulation layer provided between the front face protective sheet and the backing sheet, and encapsulating the solar battery cell. A convexly-curved portion is provided at the backing sheet to overlap the solar battery cell, and curves convexly toward a solar battery cell side, the solar battery cell curves in accordance with the convexly-curved portion, and a rigidity of the convexly-curved portion with respect to a load acting in the sheet thickness direction of the solar battery cell is higher than a rigidity of the solar battery cell.
