A production method of polyvinylidene fluoride resin particles comprising: (Process a1) a process to precipitate the polyvinylidene fluoride resin particles by adding a 100 mass% solution in total consisting of 75 to 99 mass% organic solvent, 1 to 25 mass% water and 0.5 to 15 mass% polyvinylidene fluoride resin to a poor solvent of the polyvinylidene fluoride resin; or (Process a2) a process to precipitate polyvinylidene fluoride resin particles by performing a flash-crystallization of the solution. With such a configuration, PVDF resin particles can be industrially produced by simple operations without using surfactant agent. |
