Abstract
The total thickness of a reflecting layer 12, colored layers 13 and a protecting layer 14 formed on a roughened surface area 11a of a reflecting substrate 10 is larger than a step difference Δd between the roughened surface area 11a and a flat surface area 11b so that the surface of the roughened surface area 11a of the reflecting substrate 10 is lower than the surface of the flat surface area 11b.
