Abstract
A backside covering member is used as a protective member for protecting back sides of solar cells of a solar battery and to provide moistureproof property and durability. The backside covering member includes an outer film, a moistureproof film formed on the outer film and formed of a base film and a coating layer of an inorganic oxide deposited on a surface of the base film, and a reflection layer formed on a surface of the moistureproof film opposite to a surface on which the outer film is laminated. Ethylene-vinyl acetate copolymer adhesives are situated for sealing between the outer film and the moistureproof film and between the moistureproof film and the reflection layer.
