Abstract

An amphiphilic block copolymer having an ionic functional group, wherein the ratio (N10/N5) of a rotational viscosity (N10) of a 10% by mass solution of the copolymer in purified water to a rotational viscosity (N5) of a 5% by mass solution of the copolymer in purified water is 2.5 or lower.
