Chlorinated vinyl chloride resin

The present invention provides a chlorinated polyvinyl chloride resin that enables the production of a molded article that maintains high adhesion strength even when used in a form subjected to high pressure and is less susceptible to defects such as cracks due to insufficient strength, as well as a resin composition for molding and a molded article each including the chlorinated polyvinyl chloride resin. Provided is a chlorinated polyvinyl chloride resin having an average of a ratio (A/B) of a peak intensity A observed in a range of 300 to 340 cmto a peak intensity B observed in a range of 1,450 to 1,550 cmof 0.1 or more and 3.5 or less in Raman imaging measurement by Raman spectroscopy.
