A multilayered volume hologram structure of the invention comprises a substratefor a certificate or the like, and an adhesive layer, a volume hologram layerand a surface protective filmlaminated on the substrate in the described order. When a multilayer structure consisting of the volume hologram layerand surface protective layeris forcibly released from the substrate for the purpose of making a photograph replacement or falsifying a personal information area, the volume hologram image can break down certainly, thereby ensuring prevention of falsification. A multilayered volume hologram structure-making label is useful for making a multilayered volume hologram structure.
