An artificial leather including an entangled body made of bundles of microfine fibers and an elastic polymer impregnated into the entangled body. A part of the elastic polymer penetrates into the bundles of microfine fibers. The degree of penetration of the elastic polymer is from 1 to 30% by area when measured on a cross section which is taken along a direction perpendicular to a lengthwise direction of the bundles of microfine fibers. The fiber-holding property is improved by the elastic polymer which partly penetrates into the bundles of microfine fibers, and therefore, the artificial leather has a good hand without deteriorating the surface quality.
