Abstract
Disclosed is a grain-finished artificial leather including an artificial leather base material, and a grain layer stacked on the artificial leather base material. The artificial leather base material includes a fiber-entangled body including ultrafine fibers having an average fineness of 0.4 dtex or less, an elastic polymer, and fine particles having an average particle size of 10 μm or less. The content ratio of the fine particles is 10 to 40 mass %, and the ratio of the elastic polymer to the total amount of the elastic polymer and the fine particles is 20 to 80 mass %. Also, a total of an apparent density of the elastic polymer and an apparent density of the fine particles is 0.23 to 0.55 g/cm3.
