摘要:
In order to provide artificial leather having both strength (in particular, tensile strength and tear strength), surface appearance, and a dense feeling in artificial leather including a fiber-entangled body containing a nonwoven fabric made of ultrafine fibers containing a large amount of inorganic particles (in particular, metal compounds) as a constituent element, and an elastic polymer, the artificial leather of the present invention is artificial leather including a fiber-entangled body containing a nonwoven fabric made of ultrafine fibers having an average single fiber diameter of 1.0 μm or more and 10.0 μm or less as a constituent element and an elastic polymer, and satisfies the following requirements: (1) the ultrafine fibers include a polyester-based resin containing a manganese-based compound; (2) an average particle diameter of the manganese-based compound is 0.01 μm or more and 0.20 μm or less; and (3) the ultrafine fibers contain a manganese element in an amount of 0.1 ppm or more and 50.0 ppm or less in 100 mass % of the ultrafine fiber.
