摘要： The present invention relates to a sheet-like material formed from a polymer elastic body and an entangled fiber body that includes as a constituent element thereof a non-woven fabric formed from ultrafine fibers having an average single fiber diameter of 1.0-10.0 µm, wherein the ultrafine fibers are formed from a polyester-based resin including a black pigment (a 1 ), the average particle diameter of the black pigment (a 1 ) is 0.05-0.20 µm, the coefficient variation (CV) of the average particle diameter is 75% or less, the polymer elastic body is formed from a polyurethane including a black pigment (b), and the nap covering ratio of a surface of the sheet-like material that has napping is 70-100%.
