Claim:
1. A copolymer of a conjugated diene compound and a non-conjugated olefin, comprising a copolymer including: at least one of a block sequence including monomer units of the conjugated diene compound and a block sequence including monomer units of the non-conjugated olefin; and a random sequence including randomly arranged monomer units of the conjugated diene compound and monomer units of the non-conjugated olefin, wherein each of the block sequences includes conjugated diene compound block components or non-conjugated olefin block components having an absolute molecular weight of more than 10,000 and the random sequence includes conjugated diene compound block components or non-conjugated olefin block components having an absolute molecular weight of 10,000 or less, and wherein the content of a long-chain non-conjugated olefin component having a number-average molecular weight (Mn) of 40,000 or more, which refers to the block sequence including monomer units of the non-conjugated olefin, is more than 1 mass % to 20 mass % of the total non-conjugated olefin component in the copolymer.
