摘要：
A norbornene-based polymer contains at least one kind of a repeating unit represented by the following formula (I): wherein R1 and R2 each represent a hydrogen atom, an alkyl group which may possess a substituent group or an aryl group which may possess a substituent group, L and L′ each represent a bivalent linking group or a single bond, and A and A′ each represent an aromatic group.
