摘要 Disclosed is a leather-like sheet including a fiber bundle entangled body which is an entangled body of a fiber bundle of ultrafine filaments. A fiber occupancy (A1) of a superficial layer that is a zone covering ⅔ of the thickness from a front surface of the fiber bundle entangled body, is 36 to 56 vol %. A fiber occupancy (A2) of a bottom layer thereof that is a zone covering ⅓ of the thickness from a back surface, is smaller than the fiber occupancy (A1). A ratio (A1/A2) of the fiber occupancy (A1) to the fiber occupancy (A2) is 1.08 to 1.8.
