摘要

A backside covering member (1) for a solar battery is made by integrally laminating an outer film (3) and a moistureproof film (2) with EVA adhesives (4). The moistureproof film (2) is constituted of a base film and a coating layer of an inorganic oxide deposited on a surface of said base film. A backside covering and sealing film is made by integrally laminating the aforementioned backside covering member (1) and an EVA film (6) together. A solar battery (10) is made by sealing solar cells (7) between a front side transparent protective member (8) and the aforementioned backside covering member (1) as a back side protective member. The present invention provides a backside covering member for solar battery and a backside covering and sealing film which are light and thin, are excellent in moistureproof property and durability, further have good insulation performance, and do not cause leakage of current and a durable, high-performance solar battery using the aforementioned backside covering member as a back side protective member.
