An aqueous emulsion which contains an ethylene-vinyl alcohol copolymer (A) that serves as a dispersant and a polymer (B) that contains an ethylenically unsaturated monomer unit and serves as a dispersoid, wherein: the ethylene-vinyl alcohol copolymer (A) has an ethylene unit content of 1% by mole or more but less than 20% by mole; and the crystallinity in water at 30°C (Cw (30°C)) and the crystallinity in water at 70°C (Cw (70°C)) as determined by pulse NMR satisfy formula (I). Consequently, the present invention provides an aqueous emulsion which forms less aggregates, while having excellent water-resistant adhesiveness and excellent film formability.
