Abstract: PROBLEM TO BE SOLVED: To obtain a solar cell sealing material which is mainly formed of ethylene-vinyl acetate copolymer, high in volume resistivity, and used as a laminated sealant. SOLUTION: When ethylene-vinyl acetate copolymer which contains 30 wt.% vinyl acetate or below is used as solar cell sealing material, a solar cell module is improved in insulation even if it is sealed up with a thin layer of the above sealing material. Furthermore, two sheets of the solar cell sealing material are prepared, and a film formed of material other than ethylene-vinyl acetate copolymer is sandwiched in between the solar cell sealing material sheets for the formation of a three-layered laminate more enhanced in volume resistivity.
