Abstract

The present invention provides a mirror surface decorative sheet having excellent specularity, excellent surface properties, and excellent processability in which neither springback nor cracking occurs during the processing steps, and a mirror surface decorative plate using this mirror surface decorative sheet. The present invention relates to a mirror surface decorative sheet comprising at least a base sheet and a surface-protecting layer, and having a crack elongation as measured by a predetermined method of 10 to 20%, the base sheet being formed of a polypropylene resin, the base sheet having a thickness of 150 to 500 μm, and the base sheet having a ten-point mean roughness (Rzjis) of a surface as measured according to JIS B 0601: 2001 of 5 μm or less, the surface-protecting layer being a cured product of an ionizing radiation-curable resin composition, the surface-protecting layer having a thickness of 7 to 17 μm.
