PROBLEM TO BE SOLVED: To provide a lighting device in which a color of a filter element is hardly seen.SOLUTION: A lighting device 100 includes a light emission module 130, a housing 120 having an emission port 122 for emitting the light from the light emission module 130, and accommodating the light emission module 130, and a filter element 160 disposed between the light emission module 130 and the emission port 122 in the housing 120, and cutting a wavelength component of a part of the light from the light emission module 130. A≤8×L is satisfied when a length of an outline of the filter element 160 when visually observing the same form an outer side of the housing 120 is A [mm], and a clearance between the light emission module 130 and the filter element 160 is L [mm].SELECTED DRAWING: Figure 6 【課題】フィルタ素子の色が見えにくい照明装置を提供する。【解決手段】照明装置１００は、発光モジュール１３０と、発光モジュール１３０からの光が出射される出射口１２２を有し、発光モジュール１３０を収容する筐体１２０と、筐体１２０内の発光モジュール１３０と出射口１２２との間に設けられ、発光モジュール１３０からの光の一部の波長成分をカットするフィルタ素子１６０とを備え、筐体１２０の外側から視認した場合のフィルタ素子１６０の輪郭の長さをＡ［ｍｍ］、発光モジュール１３０とフィルタ素子１６０との間隔をＬ［ｍｍ］とした場合、Ａ≦８×Ｌである。【選択図】図６
