Reflective sheet

Provided is a reflective sheet that includes a reflective layer having a wide reflection wavelength range, excellent diffusion reflection properties, and inconspicuous defects. The reflective sheet includes a plurality of reflective layers that are laminated, the reflective layers being obtained by immobilizing a cholesteric liquid crystalline phase, in a cross-section of the reflective layer observed with a scanning electron microscope, at least a part of bright portions and dark portions derived from the cholesteric liquid crystalline phase has a flapping structure, a helical pitch in one or more reflective layers changes in a thickness direction, and a thickness of a reflective layer that is formed on a surface other than a surface of the reflective layer is less than those of other reflective layers.
