1. An olefin resin comprising a copolymer of an olefin macromonomer with a non-conjugated diene,
wherein the non-conjugated diene is selected from chain dienes, cyclic dienes, and a polyolefin polymer containing vinyl groups at both chain ends which contains constituent units derived from at least one selected from the group consisting of ethylene (a), α-olefins having 3 to 20 carbon atoms (b), and cyclic olefins (c) represented by formulas [I], [II], and [III] below, wherein
1) the vinyl termination ratio to both chain ends of all molecular chains is 70% or more, and
2) the intrinsic viscosity [η] measured in a decalin solution at 135° C. is in a range of 0.01 to 10 dl/g,
