PROBLEM TO BE SOLVED: To enable a deep drawing decorative sheet to be pneumatically formed into a three dimensional shape even at a so-called low temperature of≤120°C and under the so-called low pressure of≤5.1 MPa. SOLUTION: In a metal tone decorative sheet, wherein at least a metal layer 24 is laminated on a thermoplastic substrate sheet 21, which is used by being pneumatically formed into a three-dimensional shape, where a surface temperature of the metal tune decorative sheet before the deformation is x (°C) and atmospheric pressure applied to the metal tune decorative sheet is y (MPa), a condition of 5.1≥y≥-x/20+4.6 is satisfied under a condition of 40°C≤x≤90°C and a condition of 5.1≥y≥0.1 is satisfied under a condition of 90°C≤x≤120°C.
