Abstract: A task to be achieved by the invention is to provide a fiber substrate having excellent filling state of a urethane resin and excellent hand feeling. The present invention provides a fiber substrate filled with a urethane resin (X), which is formed from a water dispersion of the urethane resin (X), wherein the water dispersion has a urethane resin (X) content of 50 to 80% by mass, and the water dispersion contains no organic solvent. Further, the present invention provides an artificial leather having the above-mentioned fiber substrate. It is preferred that the urethane resin (X) uses a chain extender (a1) as a raw material.
