According to the present invention, a transfer material 5 is prepared, which has a multilayer sheet 1 comprising: a substrate sheet 2; and a protective layer 3 disposed on one surface of the substrate sheet 2 to protect at least a portion of the surface of a sealing material 13, wherein the protective layer 3 is the outermost layer of the multilayer sheet 1 and contains an active energy ray-cured or -semi-cured product of an active energy ray-curable resin. The transfer material 5 has a polysiloxane chain and a heat-reactive group which can undergo a thermosetting reaction with a mold raw material 18 and/or a semi-cured mold 19. The mold raw material 18 and/or the semi-cured mold 19 are prepared, the transfer material 5 is disposed so as to expose the protective layer 3, the mold raw material 18 and/or the semi-cured mold 19 and the protective layer 3 are brought into contact with each other and heated, and a hard coat layer 14 obtained by thermally curing the protective layer 3 is transferred to the sealing
