Abstract
A napped artificial leather includes: a non-woven fabric that is art entangled body of ultrafine fibers, and an elastic polymer applied into the non-woven fabric; where the napped artificial leather has, on at least one side thereof, a napped surface formed by napping the ultrafine fibers. Each of the ultrafine fibers is art ultrafine fiber having a fineness of 0.5 dtex or less, and a tensile strength of 6 to 9 mN. A plurality of the ultrafine fibers form a fiber bundle, and the ultrafine fibers that form the fiber bundle are not constrained by the elastic polymer in a region of the napped artificial leather other than a surface layer portion. A content ratio of the elastic polymer is 16 to 40 mass %, and the napped artificial leather has an apparent density of 0.38 g/cmor more.
