PROBLEM TO BE SOLVED: To provide a leathery sheet excellent in abrasion resistance and surface quality and capable of being composed substantially of fiber materials by decreasing polymer elastic materials, and to provide a manufacturing method of the leathery sheet excellent in process passage in high speed fluid treatment. SOLUTION: The leathery sheet is obtained by laminating a nonwoven fabric (A) comprising a fiber of 0.0001-0.5 decitex average single fiber fineness on one side surface of a woven or a knitted fabric (B) having≥200 cc/cm<SP>2</SP>/sec airflow quantity, and a nonwoven fabric (C) of 0.2-1.0 decitex average single fiber fineness on the other side surface.
