Abstract
An anti-counterfeiting apparatus is capable of preventing delamination between layers laminated in an anti-counterfeiting device through a structural color expressed by a load and images formed by the structural color. The anti-counterfeiting apparatus may include a first layer formed of a flexible material and including a high-corrugation region and a low-corrugation region, a second layer formed on an upper portion of the high-corrugation region in a pattern, to be adhered to the first layer, and formed of a material having a Young's modulus greater than that of the first layer, and a third layer adhered to the first layer to cover the low-corrugation region and the second layer, and formed of a material having a Young's modulus greater than that of the first layer and a Young's modulus smaller than that of the second layer.
