PROBLEM TO BE SOLVED: To obliterate the need for the separation of non-hollow particles by directly preparing only hollow polymer particles having fine bubbles 2 as nuclei.SOLUTION: The provided manufacturing method of hollow polymer particles in which polymer shells having fine bubbles 2 as nuclei are formed by polymerizing a polymerizable compound 1 via a polymerizing reaction comprises a bubble generation step of generating fine bubbles 2 within a solution 3 provided by diluting a polymerizable compound 1 with a solvent 4 and a size adjustment step of adjusting sizes of fine bubbles 2 within the solution 3. At the size adjustment step, sizes of the fine bubbles 2 are reduced to less than those at the time of dispersion so as to elevate the concentration of the polymerizable compound 1 in the vicinity of fine bubbles 2 to a concentration capable of inducing polymerization based on molecule transports of the polymerizable compound 1 and solvent 4 occurring due to size changes of the fine bubbles 2. |
