The invention relates to a safety element used for providing safety guarantee for valuable objects. The safety element is equipped with a reflection layer of a first main surface and a reflection layer of a second main surface, both of which are opposite. A miniature structure is arranged on a first part region. A second part region does not have a miniature structure. The safety element is provided with a dielectric medium spacing layer subjected to vapourplating operation. The dielectric medium spacing layer is positioned between a first absorption layer and a reflection layer threof in two part regions on the side of the first main surface. A first intervention layer element is formed on the dielectric medium spacing layer. When observing from the first main surface, color tilting effect is displayed on the first part region and the second part region. The safety element has the dielectric medium spacing layer subjected to stamping operation. The dielectric medium spacing layer is positioned between a second absorption layer and a reflection layer threof in two part regions on the side of the second main surface. A second intervention layer element is formed on the dielectric medium spacing layer. When observing from the second main surface, metal appearance with a color tilting effect is not displayed on the first part region. The color tilting effect is displayed on the second region.
