To secure preferable contrast between a part where a predetermined pattern is positioned and its adjacent part, when a design layer is viewed with an illuminating device on.SOLUTION: A decorative component 2 in which a predetermined pattern 3 is visible when an illuminating device 30 provided on a back surface is turned on and the predetermined pattern 3 is invisible when the illuminating device 30 is turned off, includes: a light shielding layer 15 in which laser processing portions 17 for transmitting light of the illuminating device 30 are formed in a predetermined pattern 3 and that has a material that reacts to laser light; a transparent layer 14 that is placed on a surface of the light shielding layer 15 in the form of layers and is made of a material that does not react to laser light; and a design layer 13 that is placed on a surface of the transparent layer 14 in the form of layers and has a predetermined transmittance at which light is transmitted when the illuminating device 30 is turned on and the predetermined pattern 3 is invisible when the illuminating device 30 is turned off; wherein the design layer 13 and the transparent layer 14 have substantially the same refractive index.SELECTED DRAWING: Figure 2

    【課題】照明装置の点灯時に意匠層を見た際に、所定パターンが位置する箇所とその隣接箇所との間で好ましいコントラストを確保する。【解決手段】背面に設けられる照明装置30の点灯時に所定パターン3が視認可能であり、照明装置30の消灯時に所定パターン3が視認不能である加飾部品2は、照明装置30の光を透過させるレーザ加工部17が所定パターン3に形成され、レーザ光に反応する材料を有する遮光層15と、遮光層15の表面に積層され、レーザ光に反応しない材料からなる透明層14と、透明層14の表面に積層され、照明装置30の点灯時に光を透過させ、照明装置30の消灯時に所定パターン3が視認不能になる所定の透過率を有する意匠層13と、を備え、意匠層13と透明層14とは、実質的に同一の屈折率を有する。【選択図】図2
