PROBLEM TO BE SOLVED: To provide a reflection member for an illumination fixture wherein light is enabled to be distributed in an oval state and wherein relation of the major axis and the minor axis can be freely designed. SOLUTION: This is a reflection member for an illumination fixture having a reflecting face 110 that is concave toward the inside, and at the reflection face 110, plural small reflecting faces 150 of convex shape are formed with a fixed interval. In these small reflecting faces 150, the radius of curvature r1 on the major axis X side of the light distributed in the oval state and the radius of curvature r2 on the minor axis Y side of the light distributed in the oval state are different. Besides, the radius of curvature r1 of the major axis X side of the light distributed in the oval state is set smaller than that of the curvature r2 of the minor axis Y side. |
