Abstract: An anti-counterfeiting structure includes a substrate having a surface, and a device structure positioned on the surface. A side opposite to the side on which the substrate is positioned with respect to the device structure 12 is an observation side, and the device structure comprises an optical device layer that emits predetermined light towards the observation side, the optical device layer including a relief structure layer, and an information portion that contains given information. The information portion comprises a first substance having optical transparency, wherein the first substance is changeable to a second substance having a different optical characteristic from the first substance by laser irradiation, and the second substance representing information. The information portion is constituted by a plurality of information elements. The device structure has a display surface that is a surface opposite to the surface on which a surface of the substrate, and is configured so as to display information contained in the information portion via the display surface. After laser irradiation each of the information elements includes the first substance dispersed substantially throughout the entire information element and the second substance dispersed substantially throughout the entire information element, and has a shape representing a portion of the information as viewed perpendicular to the surface. In a portion of the relief structure layer contacting an information element, a discolored changed portion, that is a portion having a color different from that of a portion other than the discolored changed portion in the relief structure layer, is formed by the laser irradiation.
