The water-borne urethane resin composition of the present invention comprises (1) a water-borne urethane resin having a heat-sensitive coagulation temperature of 40 to 90° C. and (2) an associated type thickener. In the method of producing a fibrous sheet-like composite according to the present invention, (i) a fibrous material substrate is impregnated or coated with (ii) the water-borne resin composition and then (iii) heat-sensitive coagulation is performed using steam.
