PROBLEM TO BE SOLVED: To provide a reflection sheet which is thinned, has high reflectance and increases diffuse reflecting property. SOLUTION: The reflection sheet is constituted by sticking a thin porous resin sheet and a plastic sheet having a metallic thin film layer with an adhesive or a pressure sensitive adhesive in a rugged pattern. The reflection sheet is processed to meet purposes and used for an illuminator and a display device. Thus, the reflection sheet is thinned, the reflectance of light on a long wavelength side is made high, and also the warpage deformation amount of the sheet itself is made small and processability is increased in spite of a reflection sheet body using the porous sheet.
