Zusammenfassung:	To provide a cover member for light sources with which it is possible to prevent or suppress dew condensation from occurring on inside faces.SOLUTION: Provided is a cover member for light sources that is installed on an emission side of a light source, and that comprises: a substrate composed mainly of a resin material and having light permeability; and a conversion layer provided on one face side of the substrate and including a wavelength conversion material converting some of incident light to an infrared ray. The conversion layer is installed located facing the light source side. The conversion layer is heated by the infrared ray derived by wavelength conversion.SELECTED DRAWING: Figure 1 【課題】内側の面に結露が生じるのを防止または抑制することができる光源用カバー部材を提供すること。【解決手段】光源の出射側に設置される光源用カバー部材であって、主として樹脂材料で構成され、光透過性を有する基材と、前記基材の一方の面側に設けられ、入射する光の一部を赤外線に変換する波長変換材料を含む変換層と、を備え、前記変換層が前記光源側に位置する向きで設置されるものであり、前記変換層は、波長が変換された前記赤外線によって発熱することを特徴とする光源用カバー部材。【選択図】図１
