REFLECTION SUPPRESSION FOAM SHEET

To provide a new reflection suppression member having low reflectance.SOLUTION: A reflection suppression foam sheet contains a resin foam layer, in which the foam layer contains a resin component and a black coloring agent, a thickness T of the foam layer is 70-1,200 μm, a void ratio from the surface of the foam layer to a thickness 0.1T is represented by P0.1, a void ratio from the surface of the foam layer to a thickness 0.3T is represented by P0.3, and a void ratio from the surface of the foam layer to a thickness 0.5T is represented by P0.5, P0.1>P0.3>P0.5, and P0.1 is equal to or greater than 80%.SELECTED DRAWING: None 【課題】 低い反射率を有する、新規な反射抑制部材を提供すること。【解決手段】 樹脂発泡層を含む反射抑制発泡シートであって、発泡層は樹脂成分と黒色着色剤とを含み、発泡層の厚みＴが７０〜１２００μｍであり、発泡層の表面から厚み０．１Ｔまでの空隙率をＰ０．１とし、発泡層の表面から厚み０．３Ｔまでの空隙率をＰ０．３とし、発泡層の表面から厚み０．５Ｔまでの空隙率をＰ０．５とした場合に、Ｐ０．１＞Ｐ０．３＞Ｐ０．５であり、Ｐ０．１が８０％以上である、反射抑制発泡シート。【選択図】なし
