PROBLEM TO BE SOLVED: To provide an aqueous emulsion which has a low viscosity in spite of having a high solid content concentration, and has not only excellent sedimentation stability but also excellent mechanical stability and skinning resistance. SOLUTION: This aqueous emulsion containing an ethylenic unsaturated monomer unit-having polymer (A) as a dispersoid and PVA (B) having 1,2-glycol bonds in an amount of≥1.9 mol.%, a polymerization degree of≥300 and a saponification degree of≥70 mol.% as a dispersant in a (B)/(A) weight ratio of 1/100 to 3/100, and having a solid content concentration of≥55 wt%, an emulsion viscosity of≤2,000 mPa s, and an average particle diameter of 1 to 2μm.
