The invention provides a hologram transfer foil ( 1 ) comprising, that includes, in order from top to bottom, a substrate ( 7 ), a volume hologram layer ( 2 ) releasably stacked on substrate ( 7 ) and comprising a volume hologram in a cured resin layer, a first heat seal layer ( 3 ) and a second heat seal layer ( 4 ). In use, the hologram transfer foil ( 1 ) is applied on the second heat seal layer ( 4 ) side over an application member. The adhesion force of volume hologram layer ( 2 ) to the application member is larger than a material fracture force for the volume hologram layer or the application member, so that the hologram transfer layer can be applied by thermo-compression to the application member. This hologram transfer foil is useful for illegal copying of the hologram layer because when the volume hologram is forcibly peeled from the application, a material fracture of the volume hologram layer or application member occurs. When a colored layer functioning as a back layer is provided, it is possible to obtain a hologram transfer foil which eliminates any adverse influence of a coloring component on the volume hologram layer.
