Provided is a method for producing purified chloroprene-based-polymer latex which enables efficiently removing a residual volatile organic substance from chloroprene-based-polymer latex while suppressing foaming and the deposition of aggregates. The method for producing purified chloroprene-based-polymer latex of the present invention has at least the following steps (I) to (III): Step (I): a step of introducing chloroprene-based-polymer latex into a container beforehand, Step (II): a step of removing a residual volatile organic substance in the chloroprene-based-polymer latex which satisfies specific requirements (1) to (4), and Step (III): a step of collecting the latex from the container after performing the step (II) at least once, to thereby obtain purified chloroprene-based-polymer latex.
