Then, the preliminary irradiation of ultraviolet ray permeating only near the surface of this decoration layer 22D is performed to form a fine surface height variation portion 23 by shrinkage of ink in the surface of the ink printing portion of the decoration layer 22D. Thereafter, the complete irradiation of ultraviolet ray permeating through the total thickness of the decoration layer 22D is performed to completely harden the total thickness of the decoration layer 22D while maintaining the surface height variation portion 23. This enables the matting of the decoration layer in a controlled state without applying a topcoat.
