To provide a polychloroprene-base latex having improved adhesiveness and water resistance over conventional polychloroprene-base latex adhesives. A polychloroprene-base latex containing 2% or less by weight of a conventional emulsifier, and an acid functional group-terminated polychloroprene-type polymer represented by the following formula (1) or a polychloroprene-base random copolymer with hydrophilic group, and a method for producing the polychloroprene-base latex: <?in-line-formulae description="In-line Formulae" end="lead"?>(polychloroprene-type polymer)-S-R-X (1)<?in-line-formulae description="In-line Formulae" end="tail"?> (wherein X represents a carboxyl group or its salt; represents an alkyl group, an aryl group, a substituted alkyl group or a substituted aryl group).
