The invention relates to a security element (2), for radio frequency identification, as well as to a method for producing said security element. The security element comprises a flexible, electrically non-conductive substrate layer (24) and a conductive layer (29) applied on the substrate layer, said conductive layer being made of an electrically conductive material and shaped, in a first surface area of the substrate layer according to a pattern, to form a radio frequency component. In the surface area which is associated with the RF component, a first relief structure (27) is formed in the first conductive layer (29), at least in sections thereof.

L'invention concerne un élément de sécurité (2) pour l'identification par radiofréquence, ainsi qu'un procédé de production d'un tel élément de sécurité. Cet élément de sécurité présente un substrat (24) souple, non électroconducteur et une couche (29), conductrice, qui est appliquée sur ce substrat, est constituée d'un matériau électroconducteur et est mise en forme dans une première zone de la surface de la couche de substrat, selon un motif, pour constituer un composant à radiofréquence. Dans la zone superficielle associée au composant à radiofréquence, une première structure à relief (27) est formée, au moins dans certaines zones, dans la première couche (29), conductrice.
