<p>A cyclic olefin polymer is provided and includes a repeating unit represented by formula (1A) and a repeating unit represented by the formula (1B): R1 and R3 each independently represents a substituent, L1 and L2 each independently represents a single bond or a divalent linking group, m and p each independently represents an integer of 0 or 1, and n and q each independently represents an integer of 1 to 4; and A represents COOR2 or OCOR2, and R2 represents a linear alkyl group having a carbon number of 1 to 10. The cyclic olefin polymer has a copolymerization ratio of x and y satisfying 0.03<=y/(x+y)<=0.50, a number average molecular weight of from 70,000 to 300,000, and a weight average molecular weight of from 200,000 to 700,000.</p> |
