PROBLEM TO BE SOLVED: To provide a vehicular lighting device capable of allowing light emission by a plurality of LED light sources to be visually recognized as uniform as much as possible even in the case where an inner lens is inclined with respect to a substrate.SOLUTION: A vehicular lighting device 16 includes: a plurality of first LED light sources A for allowing a first inner lens 91 to transmit irradiation light; a plurality of second LED light sources B for allowing a second inner lens 92 to transmit irradiation light; and a first substrate 95 in which the first LED light sources A and the second LED light sources B are mounted on a single flat surface. It also includes: third LED light sources C for allowing the second inner lens 92 to transmit irradiation light; and a second substrate 100 on which the third LED light sources C are mounted and which is disposed on the depth side of the first substrate 95, in a front view of the lighting device 16. The second inner lens 92 is at least inclined in a vehicle front and back direction with respect to the first substrate 95. At the second substrate 100, a driver part 102 for supplying power to each LED light source is disposed so as to be superposed with the substrate 95 in the front view of the vehicular lighting device 16.SELECTED DRAWING: Figure 9

    【課題】基板に対してインナレンズが傾斜している場合でも複数のLED光源による発光を極力均一に視認させることができる車両の灯火装置を提供する。【解決手段】第1インナレンズ91に照射光を透過させる複数の第1LED光源Aと、第2インナレンズ92に照射光を透過させる複数の第2LED光源Bと、第1LED光源Aおよび第2LED光源Bを単一平面上に実装する第1基板95とを含む車両の灯火装置16において、第2インナレンズ92に照射光を透過させる第3LED光源Cと、第3LED光源Cを実装すると共に、灯火装置16の正面視で、第1基板95の奥側に配設される第2基板100とを具備する。第2インナレンズ92は第1基板95に対して少なくとも車体前後方向に傾斜している。第2基板100に、各LED光源に電力を供給するドライバ部102を、車両の灯火装置16の正面視で第1基板95と重なるように配設する。【選択図】図9
