PROBLEM TO BE SOLVED: To provide a solar battery module in a highly reliable structure, without the peeling of an adhesive material/sealing material from a reinforcing plate, even at the time of being exposed in outdoors for a long time, and capa ble of being manufactured at a low cost by lowering material costs. SOLUTION: A solar battery module is provided with a solar cell element 301, for which single or plural photovoltaic elements provided with at least one semiconductor layer as an optical conversion member are connected, a light-receiving surface side covering material provided with a transparent member 303 on the front-most surface and the sealing material 302a disposed between the transparent member 303 and the solar cell element 301, and a non light- receiving surface side covering material provided with a reinforcing material 306 on a backmost surface and the adhesive material 305 disposed between the reinforcing material 306 and the solar cell element 301 for sticking together the solar cell element 301 and the reinforcing material 306. The reinforcing material 306 is provided with organic resin layers on both surfaces, and the thickness of the organic resin layer on the side of the solar battery element 301 is made thinner than the thickness of the organic resin layer on the side opposite to the solar cell element 301. |
