Summary:Provided are: a manufacturing method for polymer particles, including: mixing a polymer solution, which is obtained by dissolving a polymer in a good solvent, and a polymer non-solvent, which is a non-solvent for the polymer and has compatibility with the good solvent, in a continuous or intermittent manner; and allowing a mixed solution of the polymer solution and the polymer non-solvent to flow down through a tubular bodyprovided substantially vertically, thereby completing the precipitation of polymer particles; and a manufacturing apparatus for polymer particles. The manufacturing method enables the manufacture of polymer particles which have a relatively narrow particle diameter distribution even when the polymer particles are kept in a dispersion solution state.
