A lowly crystalline polypropylene sheet which has an average spherulite radius of 0.1 to 4 mu m, an average spherulite number of up to 600 per mm<2> in a cross section of the sheet, and a solid density of 0.895 g/cm<3> or lower, gives a differential scanning calorimetry (DSC) curve in which the enthalpy of melting ( DELTA H) for the maximum endothermic peak is less than 90 J/g, has a gloss of 90% or higher on at least one side, has an exothermic peak of 1 J/g or higher on the lower-temperature side of the maximum endothermic peak, and has a thickness of 50 mu m or larger. |
