Patent number: 12163653Abstract: A decorative sheet includes, from the front side to the back side, a skin layer, an intermediate layer, a design layer, and a soft layer. Recesses open on at least one of a front surface and a back surface of the design layer. The decorative sheet further includes display regions formed by the recesses.
