The decorative member 10 is visually recognized from the side of the surface of the transparent base material 11 on which the transparent layer 12 is not formed, and is visually recognized as if characters and patterns are displayed on the surface-treated metal surface. Hereinafter, the side on which the decorative member 10 is visually recognized will be described as the front side, and the opposite side thereof will be described as the back side.

The transparent layer 12 is formed of a transparent UV ink (ultraviolet curable ink). Further, a concave-convex pattern portion 14 is formed on the back side of the transparent layer 12 (the non-contact side with the transparent base material 11). The uneven pattern portion 14 is formed as a transfer product on the surface of the metal plate 13 that has been surface-treated (see FIGS. 1 (b) and 1 (c)).

Further, on the back side (concave and convex pattern portion 14 side) of the transparent layer 12, a metal color ink, for example, a mirror surface layer 17 formed of silver is formed. Further, in the decorative member 10, a display layer 15 formed of opaque ink, for example, black ink, white ink, or other color ink is provided between the uneven pattern portion 14 of the transparent layer 12 and the mirror surface layer 17. The display layer 15 displays characters, patterns, and the like.
