PROBLEM TO BE SOLVED: To reduce the luminance ratio of a light source part of a lighting device to a device installation surface such as the ceiling etc.SOLUTION: A lighting device 10 includes: an LED 11; a device body 12; and a cover 13. The device body 12 includes: an attachment surface 21 attached to a device installation surface 20 such as the ceiling etc.; an emission surface 22 which emits light radiated from the LED 11; and an inclined side surface 23 of which at least one part inclines to the inner side from the attachment surface 21 to the emission surface 22. The cover 13 is installed so as to cover the emission surface 22 of the device body 12 and diffuses the light emitted from the emission surface 22. The cover 13 includes a protruding part 31 which protrudes to the outer side relative to an extension surface 24 of the at least one part (the portion inclining to the inner side) of the inclined side surface 23 of the device body 12. |
