To provide an ethylene-vinyl acetate copolymer composition in which the crosslinking characteristic can be performed according to a first design even if being kept for a long period of time, and the adhesion decrease to a glass plate is prevented.
The ethylene-vinyl acetate copolymer composition includes: an ethylene-vinyl acetate copolymer; a silane coupling agent oligomer; and a crosslinking agent consisting of an organic peroxide, wherein the silane coupling agent oligomer is obtained by that 3-methacryloxy propyl trimethoxysilane is performed by hydrolysis and condensation so that the following (a) and (b) are fulfilled. (a) In an infrared absorption spectrum, the ratio of absorption of a methoxy group to absorption of a vinyl group is at most 0.05. (b) In an infrared absorption spectrum, the ratio of absorption of a silanol group that originates in the silane coupling agent oligomer to absorption of a vinyl group is at least 0.4.
