PROBLEM TO BE SOLVED: To provide an easily polymerizable compound-treating apparatus which can be stably operated for a long time by preventing the generation of stagnation and polymerization of easily polymerizable gas on the apparatus side end face of a pot flange attached to the body wall of a treating apparatus for treating the easily polymerizable compound, or the like, for connecting the instruments, or the like, of a pressure gauge and a liquid-level meter. SOLUTION: In the easily polymerizable compound treating apparatus where the pot flange is attached to the body wall of the treating apparatus, the body wall side end face of a through hole formed in the pot flange is chamfered.
