Abstract: The present invention provides: a method for producing, by an eco-friendly production step, a sheet-form product that has an elegant napped appearance and that has excellent wear resistance and texture; and the sheet-form product. This sheet-form product includes a fibrous base material including ultrathin fibers with an average monofilament diameter of 0.3 to 7 [mu]m; and a water-dispersible polyurethane contained inside the fibrous base material, the water-dispersible polyurethane including both a substance having a molecular weight of 100 to 500 and having an amide bond, and inorganic particles having an average particle diameter of 1 nm to 10,000 nm. Porous particles having a BET specific surface of 5 m2/g or greater are preferably used as said inorganic particles.
