a pattern layer comprising two or more unit patterns; and
an inorganic layer formed on the pattern layer,
wherein the inorganic layer comprises a region in which a thickness t(x) of the inorganic layer formed on each unit pattern increases in a direction x in which the unit patterns are arranged.

### Claim 2 (depends on 1)

The decoration member of claim 1, wherein the area where the thickness t(x) of the inorganic layer increases comprises at least one of: an area where the thickness gradually increases, an area where the thickness continuously increases, and an area where the thickness discontinuously increases.
