To provide a lighting fixture easy to tilt a direction of light emitted from an emission surface incline to a reference optical axis.SOLUTION: A lighting fixture 1 includes a light source 2, a light guide member 3, and a fixture body 10 housing the light source 2 and the light guide member 3. The light guide member 3 is formed into an annular shape around the reference optical axis 30. The light guide member 3 includes: an emission surface 31 formed at its edge part in one direction of the axial direction of the reference optical axis 30; an incident surface 32 formed at the edge part in another direction of the axial direction; and a side wall surface 33 located between the emission surface 31 and the incident surface 32. The distance from the reference optical axis 30 of the emission surface 31 is shorter than the direction from the reference optical axis 30 of the incident surface 32.SELECTED DRAWING: Figure 1 【課題】出射面より出射される光の向きを基準光軸に対して傾斜させやすい照明器具を提供する。【解決手段】照明器具１は、光源２と、導光部材３と、光源２及び導光部材３を収容する器具本体１０と、を備える。導光部材３は、基準光軸３０の回りに環状をなすように形成される。導光部材３は、基準光軸３０の軸方向の一の向きの端部に形成される出射面３１と、軸方向の他の向きの端部に形成される入射面３２と、出射面３１と入射面３２との間に位置する側壁面３３と、を有する。出射面３１の基準光軸３０からの距離は、入射面３２の基準光軸３０からの距離よりも短い。【選択図】図１
