The purpose of the present invention is to provide: a decorative sheet that has superior scratch resistance and post-processability; and a production method for the decorative sheet. The decorative sheet (1) according to the present invention has a transparent resin layer (3) containing an olefin-based resin. A first intensity ratio which is a spectral intensity ratio between a crystalline part and a non-crystalline part of the transparent resin layer (3) as measured in the MD direction of the transparent resin layer (3) by Raman spectroscopy falls within the range of 0.9-2.0. In addition, a second intensity ratio which is a spectral intensity ratio between the crystalline part and the non-crystalline part of the transparent resin layer (3) as measured in the TD direction of the transparent resin layer (3) by Raman spectroscopy falls within the range of 0.9-1.9. Further, the sum of the first intensity ratio and the second intensity ratio falls within the range of 1.9-3.6.
