To provide a vehicular illumination device that ensures appropriate performance while achieving reduction in cost and a thickness.SOLUTION: A vehicular illumination device 1 includes a light source 50, and a lens 20 that is positioned opposite the light source 50, receives light emitted from the light source 50, and scatters the received light for emission into the vehicle cabin on a side opposite to entry of light. The lens 20 includes: a light-receiving lens face 70 that is an incident face opposite the light source 50 side, comprising a convex light incident part 72, 76 with a curved face bulging on the light source 50 side and a concave light incident part 74, 78 with a curved face indenting on the light source 50 side; and a designed lens face 80 that is the face from which the introduced light emits, and faces a cabin side.SELECTED DRAWING: Figure 6

    【課題】適切な性能を確保しつつ、コスト削減と薄型化が可能な車両用照明装置を実現する。【解決手段】車両用照明装置1は、光源50と、前記光源50と対向する位置に設けられ、前記光源50から出射された光が入射し、前記入射した光を入射側とは反対側の車両の車室内に拡散して出射するレンズ20と、を備える。前記レンズ20は、前記光源50側に面する入射面であり、前記光源50側に凸形状の曲面である凸形光入射部72,76と前記光源50側に凹形状の曲面である凹形光入射部74,78とを有するレンズ受光面70と、前記導入された光の出射面であり、前記車室側に面するレンズ意匠面80と、を有する。【選択図】図6
