PROBLEM TO BE SOLVED: To provide a ring structure-containing copolymer which substantially avoids gelation in polymerization, can give a high-concentration copolymer composition, and has excellent thermal decomposition resistance. SOLUTION: The ring structure-containing copolymer has a constitutional unit containing a ring structure derived from a 1,6-diene-2-carboxylic ester monomer and/or a 1,5-diene-2-carboxylic ester monomer.
