The aim of the present invention is to provide a water-based coating composition that has superior anti-corrosion properties, superior adhesion, and superior water resistance. The present invention pertains to a water-based coating composition containing: acrylic resin particles (A) having an acid value of 10–100 mg KOH/g, inclusive, wherein at least 80 weight% of all copolymer components is constituted by polymerizable unsaturated monomers having an SP value of 9.5 or less; and a rust inhibitor (B) that contains an aminosilane (b1), an azole compound (b2), and at least one type of compound (b3) selected from the group consisting of fatty acids, aromatic acids, and aliphatic amines. |
