A sheet-like article in which a hydrophilic-group-containing resin is applied to a fibrous base material composed of ultra-fine fibers, wherein the microphase-separated structure of the hydrophilic-group-containing resin meets the following requirement (I): (I) in a phase image obtained by observing a 1-[mu]m2 area in the cross section of the hydrophilic-group-containing resin applied to the fibrous base material by means of phase imaging using an atomic force microscope (AFM), the standard deviation of a mode of a luminance distribution in a 0.2-[mu]m2 area contained in the above-mentioned area is 0 to 10 inclusive. Provided are: a sheet-like article which is produced through an environment-friendly production process, has the same uniform quality as that of an artificial leather to which an organic-solvent-type polyurethane is applied, and also has beautiful surface quality and good texture; and a method for producing the sheet-like article.
