PROBLEM TO BE SOLVED: To provide: a sealant for a solar battery arranged by use of an ethylene-α olefin copolymer, which enables the suppression of the worsening of adhesion owing to the aging after manufacturing; and a solar battery module arranged by use of such a sealant.SOLUTION: A sealant for a solar battery comprises a composition including a resin mixture including an ethylene-α olefin copolymer and an ethylene-vinyl acetate copolymer, an organic peroxide, and a silane coupling agent. The mass proportion of the ethylene-α olefin copolymer and the ethylene-vinyl acetate copolymer is 80:20-99:1. The content of the organic peroxide is 0.5-2.0 pts.mass to 100 pts.mass of the resin mixture; and the content of the silane coupling agent is 0.1-1.5 pts.mass to 100 pts.mass of the resin mixture.SELECTED DRAWING: Figure 1 |
