The present invention is a sheet-like material having a fibrous base material composed of ultrafine fibers and the following polyurethane resin. The polyurethane resin has a structure derived from a polymer polyol, and the structure derived from the polymer polyol contains a structure derived from a polycarbonate polyol, and the following (I) to (III) or (I) (II) and (IV) ) Is satisfied. (I) The molecule | numerator of the said polyurethane resin contains a carbonate bond, an ether bond, and / or an ester bond. (II) The total of urethane groups and urea groups in the polyurethane resin is 7 to 11% by mass. (III) 80% by mass to 100% by mass of the polycarbonate polyol giving the structure derived from the polycarbonate polyol is a polycarbonate polyol having a melting point of 20 ° C. or less. (IV) 80% by mass to 100% by mass of the polycarbonate polyol giving a structure derived from the polycarbonate polyol is a polycarbonate polyol in which two or more polyhydric alcohols having different carbon skeletons are copolymerized. |
