The object of the present invention is to provide a novel ethylene-polyene that contains a specific non-conjugated polyene such as VNB as a copolymerization component, has a low content of long-chain branches, has excellent curing properties when crosslinked with a peroxide, and has good processability. Alpha-Olefin-Non-Conjugated Polyene Copolymer. The ethylene-α-olefin-non-conjugated polyene copolymer related to the present invention is characterized in that it has an α-olefin (B) with 3 to 20 carbon atoms derived from ethylene (A), and a non-conjugated polyene (C ) and satisfy specific requirements, the non-conjugated polyene (C) contains a total of two or more partial structures selected from the group consisting of the following general formulas (I) and (II) in the molecule . |
