Artificial leather and production method therefor, and composite artificial leather

Abstract

To provide an artificial leather which simultaneously achieves uniform and elegant surface quality, good touch sensation, and wear resistance while suppressing the total amount of heat generated at the time of combustion. Provided is an artificial leather including: a fiber-tangled body containing a nonwoven fabric made of fine fibers having an average single fiber diameter of 0.01 μm or more and 10.0 μm or less; and a polymer elastic body. The artificial leather satisfies the following requirements: requirement 1: the artificial leather has a weight per unit area of 25 g/m2 or more and 75 g/m2 or less; and requirement 2: the number per unit area of micropores penetrating the artificial leather in the thickness direction and having a pore diameter of 35 μm or more and 500 μm or less is 0.1/mm2 or more and 5.0/mm2 or less.
