Abstract: A multilayer inductor providing improved DC superposition characteristics by a permanent magnet that emits a bias magnetic flux, and having a low-loss material as a magnetic body to improve converter conversion efficiency. The multilayer inductor has a plurality of laminated electrically insulating magnetic layers; and laminated conductive patterns, each of the conductive patterns being connected in sequence in the lamination direction forming a spiral coil inside the magnetic layer. An magnetized annular permanent magnet layer emits a magnetic flux whose direction is opposite that of a magnetic flux excited by the coil is between an outer peripheral edge of the inductor and an outer peripheral edge of the coil so as not to overlap an inner peripheral part of the magnet layer with the conductive patterns and so as to block a space between the conductive patterns and the magnet layer, in axial view of the coil.
