Abstract
An inductor includes a core, a coil having a conductor wound around the core, and an sealing body accommodating the core and the coil. The core includes a lamination portion in which a magnetic body layer and an insulator layer are alternately laminated and is arranged such that a lamination direction of the lamination portion is orthogonal to a winding axis of the coil. The magnetic body of the core has higher magnetic permeability than the sealing body. The core has a region in which an area of a cross section orthogonal to a winding axis direction is smaller than an area of a cross section of a near-side portion in at least one direction of the winding axis of the coil.
