To further expand the usefulness of a branched polymer and to develop a branched polymer having a new structure exhibiting suitable characteristics. The present invention relates to a branched polymer comprising a support portion and at least three homopolymer chains each covalently bonded to and extending from the support portion, wherein at least three homopolymers. The chain includes a cationic homopolymer chain, a hydrophilic homopolymer chain, and a hydrophobic homopolymer chain. [Selection figure] None |
