To provide a planar lighting device which is made slim overall to be used preferably as a vanity mirror while inhibiting cost increase.SOLUTION: A planar lighting device 100 includes: lighting parts 7; and a mirror 2 laminated on the lighting parts 7. Each lighting part 7 has: a light guide plate 9 which emits light entering from a side surface to one of two major surfaces; and a single light source 8 which faces the side surface and emits the light entering into the side surface. The mirror 2 has: a mirror part; and translucent part formation areas 12b, each of which transmits the light from the lighting part 7. The single light source 8 and the side surface of the light guide plate 9 are located behind the mirror part when viewed from the mirror 2 side, one of the major surfaces of the light guide plate 9 overlaps with a translucent part when viewed from the mirror 2 side.SELECTED DRAWING: Figure 2B

    【課題】コストアップを抑制しつつ、装置全体のスリム化を図り、バニティミラーとして好適に用いることのできる面状照明装置を提供する。【解決手段】面状照明装置100は、照明部7と、照明部7に積層されるミラー2と、を備える。照明部7は、側面から入射された光を2つの主面のうち一方の主面から出射する導光板9と、側面に対向し、側面に入射される光を発する単一の光源8とを有する。ミラー2は、ミラー部と、照明部7からの光を透過する透光部形成領域12bとを有する。単一の光源8および導光板9の側面は、ミラー2側から見た場合にミラー部の背後に位置し、導光板9の一方の主面はミラー2側から見た場合に透光部と重なる。【選択図】図2B
