Abstract

In a decorative sheet, a base material has a concave portion on a front face. The concave portion includes a bottom surface. The bottom surface includes a first surface, a second surface and a third surface. A depth dimension of the first surface is a first value. The depth dimension is a dimension from the front face of the base material along a thickness direction of the base material. The depth dimension of the second surface is a second value which is smaller than the first value. The third surface is a surface which is connected with the first surface at a back side of the thickness direction, and is connected with the second surface at a front side of the thickness direction.

First claim

What is claimed is:

1 . A decorative sheet comprising:
a base material having a concave portion on a front face, wherein the concave portion including a bottom surface, wherein the bottom surface including:
a first surface whose depth dimension which is a dimension from the front face of the base material along a thickness direction of the base material is a first value;
a second surface whose depth dimension is a second value which is smaller than the first value; and
a third surface which is connected with the first surface at a back side of the thickness direction, and is connected with the second surface at a front side of the thickness direction.

2 . The decorative sheet according to claim 1 , the bottom surface further comprising:
a fourth surface whose depth dimension is a third value which is smaller than the second value; and a fifth surface which is connected with the second surface at the back side of the thickness direction, and is connected with the fourth surface at the front side of the thickness direction, wherein the first surface, the second surface and the fourth surface are surfaces which are along the front face of the base material, wherein the fifth surface is a surface having a step dimension, and the step dimension is a dimension which is along the thickness direction of the fifth surface, and the step dimension of the fifth surface has an identical value as the step dimension of the third surface.
