Zusammenfassung:To provide an illumination device that is able to suppress light leakage from an end part of a light-guide body and illuminate a part to be illuminated.SOLUTION: An illumination device includes: a light source unit 10; a light guide 20 that is a light-guide body with a long shape, guides light incident on one-end part 21 from the light source unit 10, in a longitudinal direction of the long shape toward the other-end part 22, and emits the light from a surface 23 of the light-guide body in an emitting direction substantially orthogonal to the longitudinal direction; and a housing 30 that supports the light guide 20 and has an opening 35 through which light emitted from the light guide 20 passes to illuminate an external interior panel. The other-end part 22 side of the light guide 20 is bent so as to be hidden on the back side of the interior panel 104 (a first interior panel 102) in a direction away from the opening 35, thereby constituting the illumination device 1. Accordingly, it is possible to suppress light leakage from the end part of the light-guide body and to illuminate a portion to be illuminated.SELECTED DRAWING: Figure 3 【課題】導光体の端部からの光抜けを抑制し、照射したい部分への照明を可能とする照明装置を提供する。【解決手段】光源部10と、長尺形状の導光体であって、光源部10から一端部21に入射された光を他端部22に向かって長尺形状の長手方向に光を導光し、長手方向と略直交する出射方向に導光体の表面23から光を出射するライトガイド20と、ライトガイド20を支持し、ライトガイド20から出射される光を通過させて外部の内装パネルに照射する開口部35を有する筐体30と、を有し、ライトガイド20の他端部22側は、内装パネル104(第1内装パネル102)の裏側に、開口部35から離れる方向に向かって、隠れるように屈曲して照明装置1を構成する。これにより、導光体の端部からの光抜けを抑制し、照射したい部分への照明を可能とすることができる。【選択図】図3
