1. A reflective sheet comprising:
a plurality of reflective layers that are laminated, the reflective layers being obtained by immobilizing a cholesteric liquid crystalline phase,
wherein 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, the bright portions and the dark portions appearing in a cross-sectional view of the reflective layers observed with a scanning electron microscope,
at least one of the reflective layers has a pitch gradient structure that is a structure in which a helical pitch in a thickness direction gradually increases, and
in a case where a reflective layer that is formed on a surface other than a surface of the reflective layer among the plurality of reflective layers that are laminated is set as a lower reflective layer, a thickness of the lower reflective layer is less than those of other reflective layers than the lower reflective layer in the reflective layers.
