Abstract: A liquid crystalline transfer sheet 10 includes a liquid crystal layer 12 formed on the surface of a substrate 14, where the surface hardness of the liquid crystal layer 12 is higher on the releasing surface 12A side, which is on the substrate 14 side, than on the adhering surface 12B side, which is on the receiving object 16 side. Therefore, the adhesion between the adhering surface 12B of the liquid crystal layer 12 and the receiving object 16 becomes stronger than that between the releasing surface 12A of the liquid crystal layer 12 and the substrate 14. It is thus possible to securely transfer the liquid crystal layer 12 to the receiving object 16 without leaving a part of the liquid crystal layer 12 on the substrate 14.
