PROBLEM TO BE SOLVED: To improve slipperiness without reducing transparency in relation to an independent sheet cut board and a roll sheet irrespective of a single layer or multiple layers in a polypropylene sheet and its formed products. SOLUTION: The polypropylene sheet is prepared by forming a coating film of a synthetic resin, a wax, a surfactant, an inorganic/organic fine powder, an antistatic agent and the like in 0.001-5μm thickness on at least one side of the substantially noncrystalline and nonoriented polypropylene sheet and making 1-2,000 surface protrusions/mm<SP>2</SP>having 0.1-5μm height at least on the other surface. In addition, at least either one of irregularities of various crepe patterns such as wavy, scaly, pear skin, leather crepe patterns and the like is made on the surface in combination with the surface protrusions.
