    • PROBLEM TO BE SOLVED: To provide a water-based adhesive composition which is excellent in initial adhesive power, normal adhesive power and storage stability and has adhesion reliability. SOLUTION: The water-based adhesive composition contains styrene-butadiene-acrylic copolymer latex and an aqueous solution of a silane coupling agent-hydrolyzed material. The styrene-butadiene-acrylic copolymer latex has 90/10-70/30 mass ratio of ((a styrene-butadiene portion)/(an acrylic portion)). The aqueous solution of the silane coupling agent-hydrolyzed material has ≤10 mass% concentration of a silane coupling agent in the aqueous solution if the silane coupling agent in the aqueous solution is not hydrolyzed. The water-based adhesive composition contains 0.5-15 parts mass aqueous solution of the silane coupling agent-hydrolyzed material based on 100 parts mass resin solid content of the styrene-butadiene-acrylic copolymer latex.
