Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multilayer resin sheet that hardly causes warpage due to humidity and has high transparency and high surface impact resistance.SOLUTION: The multilayer resin sheet produced by laminating (A) a resin layer including a polycarbonate resin and (B) a resin layer containing a polycarbonate resin and a polymer having an ester bond in a side chain has a thickness ratio [(B)/(A)] of the thickness of the resin layer (B) containing a polycarbonate resin and a polymer having an ester bond in a side chain to the thickness of the resin layer (A) including a polycarbonate resin is not less than 0.03 to not more than 0.3. 【課題】湿度による反りが少なく、透明性が高く、面衝撃性が高い多層樹脂シートを提供すること。【解決手段】ポリカーボネート樹脂を含む樹脂層（Ａ）および、ポリカーボネート樹脂と側鎖にエステル結合を有するポリマーとを含有する樹脂層（Ｂ）が積層された多層樹脂シートのポリカーボネート樹脂を含む樹脂層（Ａ）の厚さと、ポリカーボネート樹脂と側鎖にエステル結合を有するポリマーとを含有する樹脂層（Ｂ）の厚さの厚み比率［（Ｂ）／（Ａ）］が、０．０３以上０．３以下であることを特徴とする多層樹脂シート。【選択図】なし
