PROBLEM TO BE SOLVED: To provide an aqueous resin composition capable of forming a film excellent in adhesion to a base material, corrosion resistance, and water resistance, even at ordinary temperature. SOLUTION: This aqueous resin composition contains (A) an aqueous fatty acid-modified acrylic resin and (B) an aqueous fatty acid-modified epoxy resin, wherein the aqueous fatty acid-modified acrylic resin (A) is produced by finely dispersing a monomer mixture (I) containing a fatty acid-modified polymerizable unsaturated monomer (A1) and another polymerizable unsaturated monomer (A2) in an aqueous medium, so as to obtain a monomer emulsion having an average particle size of≤500 nm, and then polymerizing the obtained monomer emulsion, and the aqueous fatty acid-modified epoxy resin (B) contains a fatty acid (b1) and an epoxy resin (b2) having a weight-average molecular weight of≥200 as structural units.
