To provide a vehicular lighting system that can achieve light emission with even brightness in a longitudinal direction while improving productivity of a light guide body.SOLUTION: A vehicular lighting system 21 comprises a light source 24 and a lengthy light guide body 25 that extends linearly in an entering direction of light from one end arranged adjacent to the light source 24 for irradiation with light from a light emission surface 32 in a linear shape. In the light guide body 25 is formed a convex part 34 arranged in a longitudinal direction on a rear face of the light emission surface 32 and extended in a direction orthogonal to an entering direction of light. Widths W1-W12 of the convex part 34 vary depending on distances from the light source 24.SELECTED DRAWING: Figure 4 【課題】導光体の生産性を向上しながら、長手方向に均一な輝度の発光を実現することができる車両用照明装置を提供する。【解決手段】車両用照明装置２１は、光源２４と、光源２４に隣接して配置される一端から光の進入方向に線形に延び、線形状の発光面３２から光を照射する長尺の導光体２５とを備え、導光体２５には、発光面３２の背面に長手方向に配列されて、光の進入方向に直交する方向に延びる凸部３４が形成される。凸部３４の幅Ｗ１〜Ｗ１２は光源２４からの距離に応じて変化する。【選択図】図４
