PROBLEM TO BE SOLVED: To provide a resin sealing sheet having practically sufficient adhesiveness, and excellent heat resistance, capable of maintaining an excellent appearance over a long term when used as a sealing material of a solar cell, and excelling in characteristic balance.SOLUTION: A resin sealing sheet is formed by softening a thermoplastic resin to be tightly fitted thereto. The resin sealing sheet includes surface layers on the respective front and back surfaces of an intermediate layer, wherein each of the surface layers and the intermediate layer contains the thermoplastic resin; the thermoplastic resin contains an ionizing radiation crosslinking type resin; a silane coupling agent is included only in the surface layer; and an ionizing radiation irradiation treatment is performed thereto. |
