Abstract
To provide a decorative sheet including a transparent resin layer having excellent post-processing resistance and high transparency. A decorative sheet () according to one aspect of the present invention has a transparent resin layer () containing a crystalline polypropylene resin as the main component. A value of a peak intensity ratio x represented by the following expression (1) of the transparent resin layer () is x≤0.65. Herein, I997, I938, and I973 in the following expression (1) are peak intensity values calculated from the absorption spectrum obtained by Fourier infrared spectrometry of the transparent resin layer, and I997 is the peak intensity value at a wavenumber of 997 cm, I938 is the peak intensity value at a wavenumber of 938 cm, and I973 is the peak intensity value at a wavenumber of 973 cm.
