PROBLEM TO BE SOLVED: To provide a method for producing chlorinated vinyl chloride resin attaining an effective elimination of hydrogen chloride, reducing the load to the facilities in removing the by-product hydrogen chloride in the chlorinating reaction relating to a method for producing the chlorinated vinyl chloride resin obtained by chlorination of a vinyl chloride resin. SOLUTION: The invention relates to the method for production of chlorinated vinyl chloride resin comprising addition of a solvent having solubility parameter of 16-20 (MPa)<SP>1/2</SP>and≤1% of saturated solubility of water, to a water slurry of the chlorinated vinyl chloride resin obtained by chlorinating the vinyl chloride resin.
