Abstract

A conjugate having a block copolymer having a PEG chain block and a polypeptide chain block in which one molecule or more of a compound (1) represented by the following general formula (1) is bonded to an amino acid side chain constituting the polypeptide chain block with a covalent bond through the oxygen atom of the hydroxy group of the compound (1). In the general formula (1), L1 is a single bond or an alkylene group having one to five carbon atoms. Here, any methylene group in L1 may be substituted with a carbonyl group or an ether bond as long as the oxygen atoms are not adjacent to each other. X1 and X2 are each independently a hydrogen atom or a halogen atom.
