Claim 0:
1. A napped artificial leather, comprising:
a non-woven fabric comprising an entangled body of ultrafine fibers; and
an elastic polymer impregnated into the non-woven fabric;
wherein:
the napped artificial leather comprises, at least on one side thereof, a napped surface formed by napping the ultrafine fibers;
the ultrafine fibers comprise a pigment (A) in an amount of 0.5 mass % or more;
the elastic polymer comprises a positive amount of a pigment (B) in an amount up to 0.01 mass %;
the ultrafine fibers and the elastic polymer are undyed;
the napped surface has a lightness value of 25 or less in a color coordinate space (L*a*b* color space); and
a ratio of an area occupied by the elastic polymer observed on the napped surface to a total area of an area occupied by the ultrafine fibers observed on the napped surface and the area occupied by the elastic polymer observed on the napped surface is 0.5% or less.
