PROBLEM TO BE SOLVED: To provide a water-based adhesive containing a chloroprene latex as a main component, excellent in stability of viscosity with time and temperature dependence and suitable for various kinds of coating methods. SOLUTION: The water-based adhesive has 0.05-0.5μm emulsion particle diameter, 45-65% nonvolatile matter and 5-200 mPa×s viscosity at 30 rpm using Brookfield viscometer at 23°C and the adhesive comprises 100 pts. wt. chloroprene latex, 0.05-5 pts. wt. alkyl acrylate copolymer and 1-10 pts. wt. amino acid, and the adhesive has a pH adjusted to 8-9.
