A multibranched polymer represented by the following formula (I), and a method for producing the multibranched polymer: n nwhere A represents an organic group having 3 or more branched chains, X a represents a linking group containing any atom of Groups 14 to 16 in the Periodic Table, Y represents a functional group having a structure capable of having an active halogen atom, Q represents an arm moiety having a repeating unit derived from a polymerizable unsaturated bond, m 1 represents any integer of 1 to the number of branched chains of A, m 2 represents the number of branched chains of A, n 1 represents an integer of 0 or 1 or more, and R a represents an organic group that is not associated with the polymerization reaction. |
