To provide a translucent resin member which can suppress such color appearance that a translucent resin member seems to be colored according to a viewpoint position.SOLUTION: There is provided a translucent resin member 10A in which a plurality of groove structures composed of a plurality of linear projections and a plurality of linear recesses are formed on at least a part of its surface, wherein the linear projections and the linear recesses extend in a direction parallel to each other, the grooves are formed at such a pitch that transmittance of visible light which is incident in a region where the grooves are formed on the surface, and is incident at a predetermined range of an incident angle to permeate the translucent resin member becomes substantially a constant.SELECTED DRAWING: Figure 14 【課題】視点位置に応じて透光性樹脂部材が色づいて見える色見えを抑制することができる透光性樹脂部材を提供する。【解決手段】複数の線状凸部及び複数の線状凹部により構成される複数の溝構造が表面の少なくとも一部に形成された透光性樹脂部材１０Ａであって、前記線状凸部及び前記線状凹部は、互いに平行な方向に延びており、前記溝は、前記表面のうち当該溝が形成された領域に入射し前記透光性樹脂部材を透過する所定の範囲の入射角で入射する可視光の透過率が概ね一定となるピッチで形成されている。【選択図】図１４
