NOVELTY - A solar cell module has a surface protective layer (30) having gas-permeable resin film and ion impermeable layer arranged between photovoltaic cell (10) and back surface protective layer (50a), and/or gas-barrier layer arranged between photovoltaic cell and surface protective layer. A sealing material layer (20a) comprising resin which does not contain a free acid, is formed between the cell, and gas-barrier layer and/or ion impermeable layer. A sealing material layer (40a) containing resin containing ethylene-vinyl acetate copolymer, is formed adjacent to layer (30).    USE - Solar cell module (claimed).    ADVANTAGE - The evaporation of moisture content from the sealing material layer containing resin containing ethylene-vinyl acetate copolymer is favorable, therefore exposure of copolymer to outdoors in a state having moisture content and deterioration of the sealing material layer are prevented, generation of free acid is suppressed, and the durability of sealing material layer is improved. Even if water vapor passes through the surface protective layer penetrates inside the solar cell module, the gas-barrier layer prevents water vapor from reaching the photovoltaic cell, and deterioration of photovoltaic cell under the influence of water vapor is prevented.    DETAILED DESCRIPTION - A solar cell module has a photovoltaic cell, a surface protective layer arranged through a sealing material layer (20a) at the light receiving surface side of the photovoltaic cell, and a back surface protective layer arranged through a sealing material layer (40a) at the non-light-receiving surface side of the photovoltaic cell. The surface protective layer has a gas-permeable resin film and ion impermeable layer (61) arranged between the photovoltaic cell and back surface protective layer, and/or gas-barrier layer arranged between the photovoltaic cell and surface protective layer. The sealing material layer (20a) comprising resin which does not contain a free acid, is formed between the photovoltaic cell, and gas-barrier layer and/or ion impermeable layer. The sealing material layer (40a) containing resin containing ethylene-vinyl acetate copolymer, is formed adjacent to the surface protective layer.
