Claim:
1. A copolymer of a conjugated diene compound and a non-conjugated olefin, comprising a random copolymer including randomly arranged monomer units of the conjugated diene compound and of the non-conjugated olefin, wherein the random copolymer contains, by at least 5 mol %, alternate bonding units of the conjugated diene compound and the non-conjugated olefin in a unit derived from the non-conjugated olefin, and the copolymer is obtained by polymerizing a conjugated diene compound and a non-conjugated olefin in the presence of a polymerization catalyst composition containing a metallocene-based composite catalyst represented by the following formula (I): where M wherein the content of the unit derived from the non-conjugated olefin is greater than 11 mol % and not more than 20 mol %, and
