The invention relates to security element for different articles including banknotes, valuable papers, credit cards, documents, certificates and other similar articles, to a method for producing thereof and also to a counterfeit-proof material and valuable document provided with the security element. The security element has several layers each having definite optical properties which are different for each layer, such as color, reflectance, transparency, density. At the same time, at least one external layer is formed with protrusions arranged in a determined and/or random order. A lower layer is formed to be continuous while all layers together form a multilayered structure with a three-dimensional net and/or checkerboard and/or cell and/or mesh and/or linear configuration in the form of patterns, symbols, drawings, characters or codes, wherein the structure develops at least one effect amenable to visual and/or automatic inspection. The disclosed invention makes it possible to develop a simple and available security element exhibiting optimized protective properties.
