To provide an indoor lighting device for a vehicle which enables a linear portion which continues in one direction on a design surface of a vehicle interior material to be viewed in a dark place and can achieve improvement of decorative feeling.SOLUTION: An indoor lighting device for a vehicle includes: a light emitting diode 20 (a light source) disposed between a panel member 2 (a vehicle formation member) and a door trim 4 (a vehicle interior material); multiple through holes 10 which penetrate through a space between a design surface 8 and a design back surface 9 of the door trim 4 in a surface direction and which continue in one direction and are located adjacent in a linear form on the design surface 8; and a transparent material 30 which guides light emitted by the light emitting diode 20 from the design back surface 9 side to the design surface 8 side through the through holes 10. In the transparent material 30, first transparent materials 31 which are disposed along the through holes 10 on the design surface 8 side, a second transparent material 32 which is disposed along the through holes 10 on the design back surface 9 side, and third transparent materials 33 which connect the first transparent materials 31 with the second transparent material 32 through the through holes 10 are integrally provided.SELECTED DRAWING: Figure 3

    【課題】乗物用内装材の意匠面上において一方向に連続した線状の部位が、暗所においても視認でき装飾感の向上が図ることのできる乗物用の室内照明装置を提供する。【解決手段】パネル部材2(乗物構成部材)とドアトリム4(乗物用内装材)との間に介装される発光ダイオード20(光源)と、ドアトリム4の意匠面8と意匠裏面9の間を面方向に貫通すると共に意匠面8上において一方向に連続して線状に隣接する複数の貫通孔10と、発光ダイオード20から発せられる光が貫通孔10を通じて意匠裏面9側から意匠面8側に導光する導光体30と、を有し、導光体30は、意匠面8側において貫通孔10に沿って配設される第1導光体31と、意匠裏面9側において貫通孔10に沿って配設される第2導光体32と、第1導光体31と第2導光体32を貫通孔10を通じて連結させる第3導光体33と、が一体的に設けられている。【選択図】図3
