Abstract
An artificial leather including a base layer and a surface layer which is formed on one of surfaces of the base layer. The base layer includes bundles of microfine filaments and an elastic polymer. The surface layer includes the microfine filaments or includes the microfine filaments and the elastic polymer. The surface layer satisfies the relationship of X/Y≥1.5 wherein X is the number of cut ends of the microfine filaments which exist in a region from a surface to a 20 μm depth in a cross section of the artificial leather, Y is the number of cut ends of the microfine filaments which exist in a region from a surface to a 20 μm depth in a cross section perpendicular to the cross section for determining X, and X>Y. The artificial leather having such surface layer exhibits a sufficient gloss without coating a pigment such as metallic powder.
