Multilayer inductor

An inductor (1) comprising at least one first conductive layer (4a) comprising at least one first turn (5) of conductive material and at least one second conductive layer (4b) comprising at least one second turn (5) of conductive material, at least one conductive bridge (7) connecting the first and second turns (5), a layer of insulating material (6a) being interposed at least partially between the first and second turns (5), the first and second turns (5) being superimposed at least partly in the stacking direction (Z) of said layers (4a, 4b, 6a), characterized in that, in the area of superimposition of said turns, the width (I1) of the section of the first turn (5), 4a) is greater than the width (I2) of the section of the second turn (5, 4b), one of the conductive layers (4a, 4b) being formed on a substrate (3) made of paper, synthetic paper, polyethylene terephthalate, polyethylene naphthalate or polyimide.
