Provided are a solar cell encapsulant material which facilitates production of solar cell modules and which is excellent in all of adhesiveness, long-term stability of adhesion power, transparency and heat resistance, and a solar cell module produced by using the encapsulant material. The solar cell encapsulant material has at least an adhesive layer (layer (I)) and a layer (layer (II)) of a resin composition (C) that contains an ethylene-±-olefin random copolymer (A) satisfying the following requirement (a) and an ethylene-±-olefin block copolymer (B) satisfying the following requirement (b): (a) The heat of crystal fusion of the copolymer, as measured at a heating rate of 10°C/min in differential scanning calorimetry, is from 0 to 70 J/g; (b) As measured at a heating rate of 10°C/min in differential scanning calorimetry, the crystal melting peak temperature of the copolymer is 100°C or higher, and the heat of crystal fusion thereof is from 5 to 70 J/g. |
