To provide a luminaire having flat and black appearance in extinguishing of light, and capable of expressing a stereoscopic design in lighting, and a manufacturing method thereof.SOLUTION: A luminaire comprises a design plate in which a front plate and a back plate are laminated, and light irradiation means. Both sides of the front plate are flat. One surface of the back plate has a plurality of convex and concave parts, and the other surface thereof is flat. On the surface of the design plate, convex and concave parts are arranged, and the convex and concave parts are arranged in a direction facing the light irradiation means. The total light transmittance (X) of the resin constituting the front plate is 20 to 95%/2 mm, the total light transmittance (Y) of the resin constituting the back plate is 0.01-40%/2 mm, and the difference (X-Y) between the total light transmittance (X) and the total light transmittance (Y) is 10% or more.SELECTED DRAWING: Figure 5

    【課題】消灯時には、平坦かつ黒色の外観を有するとともに、点灯時には立体感のある意匠を表現することのできる照明装置及びその製造方法を提供する。【解決手段】前面板と裏面板とが積層されてなる意匠板と光照射手段とを備える照明装置であって、前面板の両面が平坦であり、裏面板の一方の表面が複数の凹凸を有し、他方の表面が平坦であり、意匠板の表面に凹凸が配置され、凹凸が前記光照射手段と対向する向きに配置されてなり、前面板を構成する樹脂の全光線透過率(X)が20〜95%/2mmであり裏面板を構成する樹脂の全光線透過率(Y)が0.01〜40%/2mmであり、かつ全光線透過率(X)と全光線透過率(Y)との差(X−Y)が10%以上である照明装置。【選択図】図5
