To easily form a gradation part by a simple configuration.SOLUTION: A decoration part 1 includes: a light-transmitting substrate 2; a non-light-transmitting undercoating layer 3 that is laminated on the light-transmitting substrate 2; and a light-transmitting overcoating layer 4 that is laminated on the undercoating layer 3. The undercoating layer 3 has laser processing traces (10a to 10g) that transmit the irradiated light on the light-transmitting substrate 2. In addition, the decoration part 1 has a gradation part 30 where the intensity of the light that is visible on the side of a design face Sa formed by the overcoating layer 4 by permeating through the laser processing traces gradually changes along the design face Sa. In the gradation part 30, clearances (d1 to d6) between the neighboring laser processing traces in a direction where the intensity of the light increases (for example, from the left side to the right side) are gradually narrowed (for example, d1>d2>d3>d4>d5>d6).SELECTED DRAWING: Figure 3
【課題】簡素な構成にて、容易にグラデーション部を形成すること。【解決手段】加飾体1は、透光性基材2と、この透光性基材2上に積層された非透光性のアンダーコート層3と、このアンダーコート層3上に積層された透光性のオーバーコート層4と、を備える。また、アンダーコート層3には、透光性基材2に照射された光を透過するレーザー加工痕(10a〜10g)が設けられる。更に、加飾体1は、レーザー加工痕を透過することによりオーバーコート層4が形成する意匠面Sa側に視認される光の強度が意匠面Saに沿って徐々に変化するグラデーション部30を備える。そして、このグラデーション部30においては、その光の強度が強くなる方向(例えば、左側から右側)に隣り合うレーザー加工痕の間隔(d1〜d6)が徐々に狭くなる(例えば、d1>d2>d3>d4>d5>d6)。【選択図】図3
