The filter is arranged on a layer that is fixedly connected to a substrate, a distance of at least 0.025 mm being present between the pattern and the filter. When the security element is tilted, the pattern or the image moves continuously. The pattern is preferably a band Moire pattern. The filter is preferably a line filter that is laser-transmissive. The pattern is preferably produced through the filter by means of a laser. The security element according to the invention is distinguished by high security against forgery and can nevertheless be produced in a comparatively cost-effective manner.
