The present invention relates to a three-dimensional micropattern using a hologram which can not be counterfeited with color copying machines or diffraction grating image forming devices. The three-dimensional micropattern comprises a hologram composed of a three-dimensional aggregation of a large number of very small micro-letters A-Z or geometric micro-figures. The micro-letters or geometric micro-figures are three-dimensionally aggregated to constitute a three-dimensional object (conical object) to allow reconstruction of a three-dimensional image of the specific three-dimensional object.
