A sealing film is used for sealing a solar cell, and including an EVA film formed of ethylene-vinyl acetate copolymer resin. The sealing film has concavities formed by embossing. A percentage defined by V /V ×100% is in a range from 20% to 50%, wherein V is the total volume of the concavities per unit area of the sealing film, and V is the apparent volume of the sealing film which is the product of the maximum thickness of the film and the unit area.
