Disclosed herein is a high-performance and highly-reliable solar cell module sealed with a solar cell sealing material which allows solar cell quality to be maintained over a long period of time due to its excellent water vapor barrier properties and adhesion properties and which has excellent recycle properties and module productivity. The solar cell module is sealed with a solar cell sealing material containing an epoxy-modified polyolefin resin composition obtained by introducing an epoxy group-containing monomer by a grafting reaction. The epoxy-modified polyolefin resin composition is preferably obtained by melt-kneading a polyolefin resin with an epoxy group-containing vinyl monomer and an aromatic vinyl monomer in the presence of a radical polymerization initiator.
