An artificial leather is provided that, due to excellent texture and mechanical strength (abrasion resistance, etc.), can be appropriately used in, for example, clothing products, or sheets of skin material or interior material, etc. for interiors, automobiles, airplanes, rail cars, etc. One embodiment of the present invention is an artificial leather that includes a fiber sheet and a polyurethane resin, wherein the fiber sheet includes a scrim that is a woven or knitted fabric, and a fiber layer (A) that constitutes a first outer surface of the artificial leather, such that in a thickness direction cross-section of the fiber layer (A), the ratio (d/D) of the total area (d) of the polyurethane resin that forms a closed shape having an area of 100 μm2 or more to the total area (D) of the polyurethane resin satisfies the following formula (1): 5≤(d/D)×100≤50 (%).
