PROBLEM TO BE SOLVED: To provide a soapless polychloroprene-based latex improving adhesion and water resistance of a conventional polychloroprene-based latex adhesive. SOLUTION: The invention relates to the soapless polychloroprene-based latex characterized by comprising 2 wt.% or less of an emulsifier and an amphiphilic chloroprene-based copolymer where a hydrophilic oligomer or polymer having an acidic functional group is attached to a hydrophobic chloroprene-based polymer, and to the method for producing the soapless polychloroprene-based latex characterized by using the amphiphilic chloroprene-based copolymer where a hydrophilic oligomer or polymer having an acidic functional group is attached to a hydrophobic chloroprene-based polymer in producing the soapless chloroprene-based latex by emulsion polymerization of chloroprene or chloroprene and a monomer copolymerizable with the chloroprene monomer.
