PROBLEM TO BE SOLVED: To provide an aqueous dispersion excellent in adhesiveness and close adhesion with various base materials, storing stability, weather resistance, waterproofness, solvent resistance, etc. SOLUTION: This aqueous dispersion is obtained by blending (I) an aqueous dispersion obtained by dispersing a block copolymer (1) constituted by (A) a polymer block consisting mainly of an olefin-based monomer unit with (B) a polymer block consisting of 2-100 mole% vinyl-based monomer unit having carboxyl group or carboxylic acid anhydride group and 98-0 mole% another vinyl-based monomer unit copolymerizable with the above vinyl-based monomer in an aqueous solution of >=0.05 equivalent basic substance based on the above carboxyl or carboxylic acid anhydride groups, with (II) a tackiness-imparting agent.
