Summary:To provide a polyester resin aqueous dispersion composition that has good storage stability, film formation properties, tackiness, adhesiveness, and water resistance. A polyester resin aqueous dispersion composition comprising a polyester resin (A), a film formation aid (B), and an aqueous medium (C), wherein among the Hansen solubility parameters of the film formation aid (B), the dispersion component ([delta]d) is not less than 15.4 MPa0.5 but less than 18.0 MPa0.5, the polarity component ([delta]p) is not less than 4.1 MPa0.5 but less than 9.1 MPa0.5, and the hydrogen bonding component ([delta]h) is not less than 7.0 MPa0.5 but less than 12.3 MPa0.5.
