Abstract: Provided is a method for producing a chemical, wherein the separation membranes can be efficiently washed and the fermentation can be stably performed in a continuous fermentation apparatus for continuously producing a chemical by fermentation using separation membranes. The method for producing a chemical by continuous fermentation according to the present invention includes a fermentation step for converting a fermentation feedstock, through fermentation by culturing a microorganism or culture cells, into a fermented liquid containing the chemical, and a membrane separation step for collecting the chemical, as a filtrate, from the fermented liquid with the use of two or more separation membrane modules, and returning the non-filtered liquid to the fermented liquid, wherein in the membrane separation step, timing of the filtration-stop treatment for each separation membrane module is controlled when an intermittent filtration operation including alternately repeating a filtration treatment and a filtration-stop treatment is performed with plural separation membrane modules.
