The graft copolymer comprises a polymerizable monomer (A1) represented by general formula (III) and a polymerizable monomer (B1) containing a pyridyl group, and a ligand can be bonded via the functional group at the terminus of R3a. In the formula, R1a represents a polymerizable group, R2a represents an alkylene group having a carbon number of 2-5, R3a represents an organic group having at a terminus a functional group selected from among an azide group, a phenyl azide group, a carboxyl group, a primary to quaternary amino group, an acetal group, an aldehyde group, a thiol group, a disulfide group, an active ester group, a trialkoxysilyl group, and a polymerizable group, and n represents any integer from 5 to 20,000.
