PROBLEM TO BE SOLVED: To provide a method for producing a highly chlorinated methane compound, capable of voluntarily adjusting a production rate of chloroform to a high purity methylene chloride in a wider range and suppressing a production amount of carbon tetrachloride, which is a by-product, at a low level. SOLUTION: Methyl chloride and methylene chloride are allowed to react with chlorine to produce the highly chlorinated methane compounds under a condition that methyl chloride may maintain a liquid phase, methylene chloride is partially separated from reaction products containing the highly chlorinated methane compounds obtained in the reaction system, and the methylene chloride is supplied to the reaction system as methylene chloride to be used for the chlorination reaction.
