Napped artificial leather

A napped artificial leather, comprising:

• a non-woven fabric that is an entangle body of ultrafine fibers;
• and
• an elastic polymer applied into the non-woven fabric, the napped artificial leather having, on at least one side thereof, a napped surface formed by napping the ultrafine fibers,
• wherein each of the ultrafine fibers is an ultrafine fiber of a polyethylene terephthalate having a fineness of 0.15 to 0.5 dtex and a tensile strength of 6 to 9 mN, and a plurality of the ultrafine fibers form a fiber bundle,
• 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,
• the elastic polymer having an expansion ratio of 0.9 to 5%,
• a content ratio of the elastic polymer is 16 to 40 mass %, and
• the napped artificial leather has an apparent density of 0.38 or more.
