To provide a vehicle indoor lighting device in which attenuation of brightness is small, and which is inexpensive.SOLUTION: A vehicle indoor lighting device comprises: a light source 610; and a translucent cover 300. The cover 300 is provided with: a light incident part 310 through which illumination light from the light source 610 is radiated; and a reflection part 320 which is formed on a surface on an opposite side of a vehicle indoor side in order to reflect the illumination light having entered into the cover 300 toward the vehicle indoor side. The light incident part 310 includes: a translucent part 311 for making a part of the illumination light from the light source 610 pass to the vehicle indoor side; and an incident part 312 for making a part of the illumination light from the light source 610 enter an internal part of the cover 300.SELECTED DRAWING: Figure 3
