Disclosed is a copolymer having a constituent unit represented by general formula (I) and a constituent unit having a photoreactive group. In general formula (I), R1, R2 and R3 independently represent a hydrogen atom or an alkyl group; and X represents a group containing at least one betaine-type group selected from the group consisting of an amidebetaine-type group, a sulfobetaine-type group, an amidesulfobetaine-type group, a carbobetaine-type group and an imidazoliniumbetaine-type group.
