The present invention provides the improvement of coating workability (e.g. pinhole resistance, sagging resistance, etc.) of an aqueous coating composition. That is, the present invention provides an aqueous coating composition which comprises: (A) an acrylic resin and/or a polyester resin having an acid value of 10 to 100, a hydroxyl value of 20 to 300 and a number average-molecular weight of 1,000 to 50,000; (B) a polycarbonate resin having a number average-molecular weight of 1,000 to 10,000 which contains a hydroxyl group at the terminal end; and (C) a curing agent.
