To provide an interior light for a vehicle, which can emit light in a wide range in a cabin of the vehicle while being downsized.SOLUTION: An interior light (10) for a vehicle includes an elongated base plate (11), a first light emission element (12) mounted on a mounting surface of the base plate (11) and configured to emit first light, a first wavelength conversion portion (13) configured to be excited by the first light to emit second light, and a light extraction portion exposed to the cabin and configured to emit second light. The light extraction portion includes a first side surface (13a) and a second side surface (13b) which are inclined to the base plate (11), and a ceiling surface (13c) located opposed to the base plate (11). A distance (H) between the ceiling surface (13c) and the base plate (11) is greater than a half of a maximum width (W) between the first side surface (13a) and the second side surface (13b).SELECTED DRAWING: Figure 1

    【課題】小型化を図りながらも車室の広範囲に光を照射することが可能な車両用室内灯を提供する。【解決手段】長尺状の基板(11)と、基板(11)の搭載面に搭載されて一次光を発光する第1発光素子(12)と、一次光により励起されて二次光を発光する第1波長変換部(13)と、車室内に露出されて二次光を照射する光取出部を備え、光取出部は基板(11)に対して傾斜した第1側面(13a)および第2側面(13b)と、基板(11)に対向する天面(13c)とを有し、天面(13c)と基板(11)との距離(H)は、第1側面(13a)と第2側面(13b)との最大幅(W)の1/2よりも大きい車両用室内灯(10)。【選択図】図1
