A vehicular interior lighting device includes a main body portion fixed to a roof, a first light source and a second light source accommodated in the main body portion, a light shielding cover portion covering the first and second light sources from below, a light guide member having a protruding portion protruding along the inside surface from a gap between the main body portion and the cover portion, and a condensing lens disposed between the second light source and the light guide member. The light guide member has a diffusion portion formed on a surface of the protruding portion facing downward and a reflecting portion reflecting light emitted from the second light source toward a part of the diffusion portion. The diffusion portion emits light in whole by light emitted from the first light source and partially emits light by light emitted from the second light source.
