PROBLEM TO BE SOLVED: To provide a water-based resin composition capable of giving a coating film excellent in adhesion to substrates and hardness and being excellent in storage stability. SOLUTION: The water-based resin composition is a water-based resin composition consisting of an aqueous medium and core/shell resin particles dispersed therein, wherein the resin component (A) which constitutes the core of each resin particles is (a) a bisphenol A derived epoxy resin of an epoxy equivalent of 400-4,000 g/eq or an amine-modified product thereof, and the resin component (B) which constitutes the shell of each resin particle is (b) a resin of a weight-average molecular weight of 3,000-10,000 obtained by reacting a polyoxyalkyleneamine (composed of 10-100, on the average, oxyalkylene units) with a bisphenol-derived epoxy resin.
