Zusammenfassung:	A method for producing a chlorinated vinyl chloride resin of the present invention includes chlorinating a vinyl chloride resin by irradiating the inside of a reactor, into which the vinyl chloride resin and chlorine have been introduced, with ultraviolet light, thereby producing a chlorinated vinyl chloride resin. The irradiation of ultraviolet light is carried out through use of at least one kind of light source selected from the group consisting of an ultraviolet LED, an organic EL, an inorganic EL, and an ultraviolet laser. A chlorinated vinyl chloride resin that shows suppressed initial coloring during hot forming and/or improved thermal stability can be provided by the method for producing a chlorinated vinyl chloride resin of the present invention.
