Abstract: A polymer compound of the present invention has a group represented by Formula (1) or Formula (2) in a side chain. (In Formula (1), X 1 represents a neutral amino acid residue or an É -aminoalkanoic acid residue, X 2 represents a membrane-permeable peptide residue, X 3 represents a hydroxyl group, an amino group, an alkoxyl group having 1 to 4 carbon atoms, or a benzyloxy group, and a represents a number of from 1 to 50.) (In Formula (2), X 4 represents a neutral amino acid residue or an É -aminoalkanoic acid residue, X 5 represents a membrane-permeable peptide residue, X 6 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a benzyl group, an acyl group having 1 to 6 carbon atoms, an arylsulfonyl group, or a carboxyl group, and b represents a number of from 1 to 50.)
