PROBLEM TO BE SOLVED: To provide: a back sheet for solar batteries, which is superior in adhesion between a polyester film and a weather resistance layer, and is arranged so as to reduce the formation of chips in cutting; a method for manufacturing such a back sheet; and a solar battery module superior in long-term durability.SOLUTION: Provided are a protective sheet for solar batteries, a method for manufacturing the protective sheet and a solar battery module. The protective sheet for solar batteries comprises: a biaxially stretched polyester film produced by stretching an unstretched polyester film in a first direction and stretching the polyester film along a film plane in a second direction orthogonal to the first direction; an undercoat layer including an acrylic resin, and formed by applying a coating liquid to one face of the polyester film stretched in the first direction before the stretching in the second direction and then, stretching the polyester film in the second direction; and a weather resistant layer including an acrylic resin and disposed on the undercoat layer.SELECTED DRAWING: None |
