An object of the present invention is to provide a solar cell sealing film that the crosslinking or curing time is reduced, and high transparency is maintained in high temperature and humidity environment over a long duration. A solar cell sealing film comprising an ethylene-unsaturated ester copolymer, a crosslinker, and crosslinking auxiliary agents, wherein the solar cell sealing film comprises a polyfunctional (meth)acrylate having 5 or more (meth)acryloyl groups in the molecule and triallyl isocyanurate as the crosslinking auxiliary agents, and a mass ratio of the polyfunctional (meth)acrylate to the triallyl isocyanurate is 0.06 to 0.3. |
