## Abstract

A method of manufacturing a decorative member, including: molding a base with a mold having a transferring surface, the transferring surface having a recessed area and the other area, the recessed area and the other area having different surface roughnesses in the base in a finished state; and treating a surface of the base molded by the transferring surface of the mold under a single condition.

## Claims

### Claim 1

A method of manufacturing a decorative member, comprising:
molding a base with a mold having a transferring surface, the transferring surface having a recessed area and the other area, the recessed area and the other area having different surface roughnesses in the base in a finished state; and
treating a surface of the base molded by the transferring surface of the mold under a single condition.

### Claim 2 (depends on 1)

The method of manufacturing a decorative member according to claim 1, wherein the recessed area of the mold is embossed whereas the other area is mirror-finished.

### Claim 3 (depends on 1)

The method of manufacturing a decorative member according to claim 1, wherein the transferred surface of the base is treated by deposition or sputtering.

### Claim 4 (depends on 2)

The method of manufacturing a decorative member according to claim 2, wherein the transferred surface of the base is treated by deposition or sputtering.

### Claim 5

A decorative member having a disk shape and having a protruding portion and the other portion on a front surface, the decorative member comprising:
a first texture portion consisting of the protruding portion comprising bosses having a predetermined size; and
a second texture portion consisting of the other portion comprising bosses having a size smaller than the predetermined size of the bosses in the first texture portion, wherein
the front surface of the decorative member is subject to a color surface treatment under a single condition.

### Claim 6 (depends on 5)

A timepiece comprising the decorative member according to claim 5.
