A laminated inductor which is adopted in an electronic circuit. The laminated inductor has a plurality of coil sections which are composed by laminating insulating layers and coil conductors alternately. The two adjacent coil sections are staggered at least either in the vertical direction or in the horizontal direction.

DETAILED DESCRIPTION An object of the present invention is to provide a laminated inductor which has a structure to decrease a cross-talk between adjacent coil sections.
In order to attain the object, a laminated inductor according to the present invention comprises a plurality of coil sections which are composed by laminating insulating layers and coil conductors alternatively, the two adjacent coil sections being staggered at least either in a vertical direction or a horizontal direction of the inductor.
In the above structure, since the two adjacent coil sections are staggered at least either in the vertical direction of the inductor or in the horizontal direction, the space between adjacent coils become larger.
Thus, the crosstalk which is caused by inductive coupling and capacitive coupling between the coil sections becomes smaller.
Further, by staggering leading sections which are connected with the two adjacent coil sections in the vertical direction, the crosstalk which is caused by the conductive coupling and the capacitive coupling between the coil sections and the leading sections can be decreased.
