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
