The present invention is a water-dispersible resin composition containing: a resin α that includes, in the main chain thereof, a structure M having two aromatic rings linked by a sulfide group, a sulfonyl group, an imide group, or a keto group; and a resin β having a hydrophilic group, the resins α and β being configured to form a co-continuous structure including three-dimensional continuous phases of the resins α and β. The present invention can provide a water-dispersible resin composition that maintains the heat resistance of the polymer material and can be removed only with water.
