Abstract

L'invention concerne un inducteur (1) comprenant au moins une première couche conductrice (4a) comportant au moins une première spire (5) en matériau conducteur et au moins une deuxième couche conductrice (4b) comportant au moins une deuxième spire (5) en matériau conducteur, au moins un pont conducteur (7) reliant les première et deuxième spires (5), une couche en matériau isolant (6a) étant intercalée au moins partiellement entre les première et deuxième spires (5), les première et deuxièmes spires (5) étant superposées au moins en partie dans la direction d'empilement (Z) desdites couches (4a, 4b, 6a), caractérisé en ce que, dans la zone de superposition desdites spires, la largeur (l1) de la section de la première spire (5, 4a) est plus importante que la largeur (l2) de la section de la deuxième spire (5, 4b).
