PROBLEM TO BE SOLVED: To provide an aqueous dispersion of a composite resin composition for adhesive capable of forming an adhesive composition having good adhesive force and mechanical stability and excellent transparency of the adhesive layer. SOLUTION: The aqueous dispersion of a composite resin composition for adhesive is produced by polymerizing a mixture containing (A) a radically polymerizable ethylenic unsaturated monomer and (B) a solid resin having a softening point of >130°C in an aqueous medium containing a surfactant, a polymerization initiator and water as essential components wherein the polymerization is carried out after forcibly emulsifying the mixture of the components (A) and (B) in the presence of the surfactant and water to obtain an emulsion having an average particle diameter of≤2μm.
