Abstract: One embodiment of the present invention relates to a chloroprene copolymer latex, a method for producing a chloroprene copolymer latex, a chloroprene copolymer latex composition, and a molded article or dipped product of a chloroprene copolymer rubber. The chloroprene copolymer latex is a latex of a chloroprene copolymer including monomer units derived from 2-chloro-1,3-butadiene (chloroprene) and monomer units derived from 2-methyl-1,3-butadiene, wherein the tetrahydrofuran insoluble content in the chloroprene copolymer is 20% by mass or less, and the proportion of the monomer units derived from 2-methyl-1,3-butadiene is 10 to 27 mol % in the chloroprene copolymer.
