PROBLEM TO BE SOLVED: To provide an aqueous dispersion having good anti-blocking property and having heat sealability particularly for a polyolefin material. An aqueous dispersion containing 100 parts by mass of the following polyolefin resin (A), 5 to 90 parts by mass of natural wax (B), and an aqueous medium. Polyolefin resin (A): a copolymer comprising an unsaturated carboxylic acid unit (A1), an ethylene-based hydrocarbon (A2), and an acrylic ester or methacrylic ester (A3), wherein (A1) to The mass ratio of the component (A3) is (A1) / {(A1) + (A2) + (A3)} = 0.01 / 100-5 / 100, (A2) / (A3) = 55 / 45-95 / Polyolefin resin satisfying 5.
