Abstract:
A decorative sheet includes a base material and a concave portion. The concave portion is provided on a front face of the base material. In the concave portion, a depth direction coincides with a thickness direction of the base material. The concave portion includes a first concavo-convex pattern and a second concavo-convex pattern. The first concavo-convex pattern is provided in a first region of an inner surface of the concave portion. The second concavo-convex pattern is a concavo-convex pattern different from the first concavo-convex pattern. The second concavo-convex pattern is provided in a second region of the inner surface of the concave portion which is different from the first region.
