This translucent resin sheet is used in a cover member (1) provided so as to cover a window part of a housing body that houses a light source that emits light and that has a window part that emits light from the light source to the outside. The translucent resin sheet (cover member (1)) has a resin layer (3) mainly composed of a resin material and a coating layer (5) laminated on at least one surface of the resin layer (3), and the coating layer (5) contains a curable resin and an ultraviolet light absorber, and is in accordance with Table 3-A method-Cycle Number 3 in JIS K 7350-2, and the coating layer (5) is in accordance with Table 3-A method-Cycle Number 3 in Table 3-A method-Cycle Number 3 in Table 3-A method-Cycle Number 3 in Table 3-A method. The color change of the translucent resin sheet measured in accordance with ISO 11664-4 after the coating layer (5) is irradiated with ultraviolet light for 600 hours using a xenon lamp weather test machine is less than 5.0 [Delta E].

    本发明的透光性树脂片用于以覆盖收纳体的窗部的方式设置的罩部件(1)中,所述收纳体收纳发出光的光源且具有使来自光源的光朝向外部射出的窗部。该透光性树脂片(罩部件(1))具有以树脂材料为主要材料而构成的树脂层(3)和层叠于树脂层(3)的至少一个表面上的涂层(5),涂层(5)含有固化性树脂和紫外线吸收剂,并且按照JIS K 7350‑2的表3‑A法‑循环编号3,使用氙灯耐候试验机向涂层(5)照射600小时的紫外线之后的按照ISO11664‑4测定的透光性树脂片的颜色变化小于5.0[ΔE]。
