Provided are a reflective sheet including a cholesteric liquid crystal layer and having excellent reflection wavelength range, diffuse reflectivity, reflectivity, hardness, and scratch resistance; and a transfer film for a reflective sheet that is used for the reflective sheet. The reflective sheet includes a substrate, an adhesive layer, a cholesteric liquid crystal layer, and a hard coat layer in this order, in which in a cross-section of the cholesteric liquid crystal layer observed, at least a part of bright portions and dark portions has a flapping structure, the cholesteric liquid crystal layer has a pitch gradient structure in which a helical pitch changes in a thickness direction, and the helical pitch on the adhesive layer side is larger than that on the hard coat layer side.
A reflective sheet comprising, in the following order:
