PROBLEM TO BE SOLVED: To provide a method for producing core-shell type polymer particles, capable of simply obtaining the monodisperse particles each having a structure composed of a hydrophilic shell and a hydrophobic core with good reproducibility in a short time and a good yield. SOLUTION: This method includes a process (A) for preparing a polymerizable solution having a concentration of 1-40 mass% by dissolving or dispersing a polymerizable material comprising a hydrophilic monomer having a polyethylene glycol chain or a phosphorylcholine group and a hydrophobic monomer copolymerizable with the hydrophilic monomer in a solvent, a process (B) for copolymerizing the polymerizable material by irradiating the polymerizable solution with a microwave, and a process (C) for purifying the monodisperse core-shell type polymer particles having an average particle diameter of 0.05-10μm from the obtained copolymer.
