A hyperbranched polymer synthesizing method employs living radical polymerization of a monomer in the presence of a metal catalyst. The method includes forming a shell portion by introducing an acid-decomposable group to a core portion formed of a hyperbranched polymer synthesized by living radical polymerization; forming an acid group by partially decomposing the acid-decomposable group by an acid catalyst; precipitating a core-shell hyperbranched polymer contained in a first solution and having the acid group, by mixing the first solution with ultrapure water; and extracting, from a mixed solution into an organic solvent by liquid-liquid extraction, the core-shell hyperbranched polymer having the acid group, wherein the mixed solution contains a second solution containing the core-shell hyperbranched polymer precipitated at the precipitating and dissolved into the organic solvent, and the ultrapure water of an amount yielding a prescribed ratio of the ultrapure water relative to the organic solvent in the second solution.
