PROBLEM TO BE SOLVED: To provide a corrugated panel good in weatherability and excellent not only in lighting properties but also in barrier properties. SOLUTION: A polycarbonate resin corrugated panel constituted by laminating a weatherable resin layer to at least the single surface of a polycarbonate resin substrate layer is employed and at least the single surface of the corrugated panel is characterized by that arithmetic mean roughness (Ra) is 5-20μm, the max. height (Ry) is 25-100μm and haze measured according to JIS K7105 is 60% or more.
