## Abstract

A decorative member includes a light-transmitting substrate which is made of resin and is formed with a recessed portion on a back surface thereof, a hot stamping foil layer which is formed on the back surface of the light-transmitting substrate except for the recessed portion, and a metal vapor deposition film layer which is laminated on the recessed portion on the back surface of the light-transmitting substrate and the hot stamping foil layer.

## Claims

### Claim 1

A decorative member comprising:
a light-transmitting substrate which is made of resin and is formed with a recessed portion on a back surface thereof;
a hot stamping foil layer which is formed on the back surface of the light-transmitting substrate except for the recessed portion; and
a metal vapor deposition film layer which is laminated inside the recessed portion on the back surface of the light-transmitting substrate and on the hot stamping foil layer, wherein
the light-transmitting substrate, the hot stamping foil layer, and the metal vapor deposition film layer are stacked in this order on a back surface side of the decorative member.

### Claim 2 (depends on 1)

The decorative member according to claim 1,
wherein a protruded portion is formed on a front surface of the light-transmitting substrate to correspond to the recessed portion.

### Claim 3 (depends on 1)

The decorative member according to claim 1,
wherein the hot stamping foil layer is black.

### Claim 4 (depends on 1)

The decorative member according to claim 1,
wherein the metal vapor deposition film layer is formed to have half mirror characteristics.

### Claim 5

A decoration method comprising:
a recessed portion forming step of forming a recessed portion on a back surface of a light-transmitting substrate which is made of resin;
a hot stamping step of applying hot stamping to the back surface of the light-transmitting substrate except for the inside recessed portion; and
a metal vapor deposition step of applying metal vapor deposition inside the recessed portion on the back surface of the light-transmitting substrate and on a hot stamping foil layer formed by the hot stamping step, wherein
the light-transmitting substrate, the hot stamping foil layer, and the metal vapor deposition film layer are stacked in this order on a back surface side of the decorative member.

### Claim 6 (depends on 1)

The decorative member according to claim 1,
wherein the recessed portion is a concave groove recessed from the back surface of the light-transmitting substrate.

### Claim 7 (depends on 5)

The decoration method of claim 5, wherein
wherein the recessed portion is a concave groove recessed from the back surface of the light-transmitting substrate.
