An object of the invention is to provide a leather-like sheet having excellent water absorbability (sweat absorbability, defined the same hereinafter), providing a natural leather-like touch, and suitably used as a ball covering or a non-slip covering, without lowering surface wear resistance. An aspect of the invention is directed to a leather-like sheet including a base material having an entangled fiber sheet; and a porous elastic resin layer laminated on a surface of the base material. The porous elastic resin layer has a concave-convex surface. The concave-convex surface of the porous elastic resin layer includes a projection having a top surface and a side surface, and a recess having a bottom surface contiguous to the side surface. The top surface of the projection has openings with a diameter from 10 to 500 nm at a density of 1,000 openings/mm2 or more.
