Zusammenfassung:	Provided is an aqueous coating composition having excellent thixotropic properties, which contributes to obtain a coating having favorable water resistance and a coated film having favorable design properties. Specifically provided is an aqueous coating composition characterized by comprising a urethane compound represented by the following general formula (1) as component (A), a flake pigment as component (B), and a water-soluble resin other than component (A) as component (C): where R 1 represents a residue obtained by removing hydroxy groups from an n-valent alcohol having 2 to 20 carbon atoms, R 2 represents a hydrocarbon group which may have a urethane bond, R 3 represents an alkyl group having 8 to 30 carbon atoms, R 4 represents an alkylene group having 2 to 3 carbon atoms, k represents an integer of 1 to 500, and n and m each represent an integer of 2 to 10.
