Abstract
A method of manufacturing a decorative sheet includes a step of stacking a light-shielding film and a design film on a surface of a base material film and a step of removing a part of the light-shielding film and a part of the design film by radiating laser light from positions on the base material film and forming transparent portions. The design film the part of which is removed forms a design layer that displays design. The light-shielding film the part of which is removed forms a light-shielding layer that covers the design layer.
