Abstract:
1. An electronic component comprising: a laminate in which magnetic layers and at least one non-magnetic layer containing glass are stacked; and a coil incorporated in the laminate, wherein a second magnetic permeability in portions of the magnetic layers which are adjacent to the non-magnetic layer is lower than a first magnetic permeability in portions of the magnetic layers which are not adjacent to the non-magnetic layer, by diffusion of the glass from the non-magnetic layer into the magnetic layers, the coil has a helical shape with a coil axis parallel to a stacking direction, the helical shape being formed by connecting a plurality of coil conductors provided respectively on the magnetic layers, and the non-magnetic layer is on each of the magnetic layers, on which the coil conductors are provided, so as to be located outside a ring shape formed by the coil conductors when viewed in plan in the stacking direction.
