Claim 0:
1. A pH-responsive polymer, comprising:
a biocompatible polymer in which a side chain thereof including a group represented by Formula (1), a group represented by Formula (2), or a group represented by Formula (3) is bonded via a linking group containing an amide bond,
wherein the biocompatible polymer is polyglutamic acid or polyaspartic acid,
wherein the linking group containing an amide bond is bonded to the main chain of the biocompatible polymer, and the side chain is electrically neutral under pH environments of 7.2 to 7.6 and which changes to be cationic under pH environments of 6.0 to 6.6:, in Formulas (1) to (3), n represents an integer of 1 to 3, and * represents a bond.
