An object of the present invention, in the manufacture of isocyanate without using phosgene, there are various problems found in the prior art, and has an isocyanate to yield to provide a method capable of producing a long-term stability. The present invention, aliphatic carboxylic acid by thermal decomposition reaction of the acid ester as a method for producing an isocyanate, a step, a carbamic acid ester from the bottom of the pyrolysis reactor to the low boiling point component from the thermal decomposition reactor is the thermal decomposition reaction formed is recovered as a gaseous component It discloses a method for producing comprising a step of supplying to an upper portion of the thermal decomposition reactor, a part or all of the process and the liquid component for collecting the liquid component containing the isocyanate.
