PROBLEM TO BE SOLVED: To provide a planar luminaire having excellent luminance and environmental resistance.SOLUTION: A planar luminaire 10 includes: a plurality of LEDs 11; an FPC 12 on which the plurality of LEDs 11 are mounted; and a light guide plate 20. The FPC 12 is fixed to a rear surface 23 of the light guide plate 20 by using a double-sided tape 15, and the plurality of LEDs 11 are arranged facing an incident surface 21 of the light guide plate 20. The double-sided tape 15 has: a white base material 16 for reflecting light; and a white adhesive layer 17 formed on a side surface facing the light guide plate 20 of the white base material 16 and reflecting light. The white adhesive layer 17 is prepared by mixing a light reflective material in an adhesive agent; thereby, luminance and environmental resistance of the planar luminaire 10 can be improved. |
