Abstract: Disclosed is a sheet-like material which is produced by an environmentally friendly procedure and has an elegant appearance with piloerection, good wear resistance and good texture. Specifically disclosed is a sheet-like material which is characterized by containing a water-dispersed polyurethane within a fibrous base that contains extra-fine fibers having an average single fiber diameter of 0.3-7 um. The sheet-like material is also characterized in that the inside of the water-dispersed polyurethane is provided with pores each having a diameter of 10-200 um. Also specifically disclosed is a method for producing a sheet-like material by applying a polyurethane liquid to a fibrous base, which is characterized in that the polyurethane liquid is a water-dispersed polyurethane liquid that contains a foaming agent and a dry film of the polyurethane that constitutes the polyurethane liquid has a 100% modulus of 3-8 MPa.
