Provided is a solar battery back sheet that is low in production costs, excellent in adhesive properties between individual constituting members thereof, and excellent in weather resistance and water-vapor-barrier performance. The back sheet has a laminated structure including at least three layers. A first layer is a weather-resistant polyester resin film or a fluororesin film; a second layer is a polyolefin layer made of a modified polyolefin resin yielded by grafting 1 to 30 parts by weight of an epoxy-group-containing vinyl monomer and 0.1 to 30 parts by weight of an aromatic vinyl monomer to 100 parts by weight of polyethylene, polypropylene or an ethylene/propylene copolymer, and which has a thickness of 5 to 250 mum; and a third layer is a polyester layer, a polyolefin layer, or an aluminum foil piece. The second layer and third layer have a total thickness of 30 mum or more. |
