PROBLEM TO BE SOLVED: To provide a method for easily producing vinylidene chloride-based resin particles having particle diameter of 1-50μm by aqueous suspension polymerization without using an organic solvent other than the monomer. SOLUTION: The vinylidene chloride-based resin particle is produced by mixing 100 pts.mass of an unsaturated monomer mixture composed mainly of vinylidene chloride with 0.2-2 pts.mass of an oil-soluble surfactant soluble in the monomer mixture and carrying out the aqueous suspension polymerization of the monomer in the presence of 0.3-3 pts.mass of a water-soluble cellulose ether having a surface tension of 40-55×10<-5> N/cm in the form of a 0.2% aqueous solution at 20 deg.C and a viscosity of 5-400 mPas in the form of a 2% aqueous solution at 20 deg.C.
