摘要：
A lamp design surface member is provided. The lamp design surface member includes a design surface having a decorative surface. Concave-convex portions and planar portions are formed together on the decorative surface. The concave-convex portions have a peak cross-sectional height Rt of 1 μm or more and the planar portions have a peak cross-sectional height Rt smaller than 1 μm. The planar portions are formed so that an area ratio of the planar portions to the decorative surface is in a range of 30% to 80%.
