To provide an artificial leather having high durability and excellent flexibility.SOLUTION: An artificial leather includes, as constituents, a fiber entangled body including a nonwoven fabric constituted of ultra fine fibers having an average single fiber diameter of 0.1 μm or more and 10.0 μm or less and a woven or knitted fabric constituted of multifilaments as constituents, and water dispersion type polyurethane. A ratio WU/WF representing a ratio of basis weight WU (g/m2) of the water dispersion type polyurethane to basis weight WF (g/m2) of the fiber entangled body is 0.20 or more and 0.50 or less. Among the multifilaments, a ratio of the number of those for which 10% or more of outer peripheries thereof come in contact with the water dispersion type polyurethane, is 0% or more and 5% or less.SELECTED DRAWING: Figure 1
