PROBLEM TO BE SOLVED: To provide a water-based coating composition forming a coating film resistant to the adhesion of stain and having easy cleanability of attached stain by a single application and forming a coating film having a thickness to get a design different from the characteristic design of the substrate attained by using a colored pigment, etc., by a single application. SOLUTION: The water-based coating composition at least contains (a) an acrylic resin emulsion, (b) silica particles, (c) water and (d) a pigment. The component (a) is a polymer produced by polymerizing at least one kind of monomer selected from a 2-7C alkyl acrylate and a 2-7C alkyl methacrylate, the average particle diameter of the component (b) is≤50 nm, and the ratio of the component (b) is 10-70 wt.% based on the total solid component.
