More Information
Summary:An inductor component includes an element body including a magnetic layer containing a resin and a magnetic powder; a coil wiring line arranged inside the element body; and an insulating coating film covering the coil wiring line and not including a magnetic material. In a cross section perpendicular to an extension direction of the coil wiring line, a top surface thickness of a part of the insulating coating film covering the top surface of the coil wiring line and a side surface thickness of parts of the insulating coating film covering side surfaces of the coil wiring line are less than or equal to 10 μm, and a corner thickness of parts of the insulating coating film that cover corners of the coil wiring line interposed between the top surface and the side surfaces is at least half of the top surface thickness and/or the side surface thickness.
