    Abstract: A DC/DC converter component has a reduced mounting area and includes an inductor component; a semiconductor integrated circuit including a switch circuit connected to the inductor component, and a control circuit that controls the switch circuit; and a package substrate, to which the semiconductor integrated circuit is mounted, having a mounting face that opposes an other substrate when the package substrate is mounted to the other substrate. The inductor component includes an element body, and a plurality of inductor wiring lines, each extending in the element body and in parallel with a main face of the element body. A value of inductance of a second inductor wiring line is 10% or more greater than a value of inductance of a first inductor wiring line. The inductor component has a dimension equal to or less than 0.25 millimeters in a thickness direction, and is mounted to the package substrate.

    Abstract: An inductor component that includes an element body; a coil wiring line that is arranged parallel to a first main surface of the element body inside the element body; and a first vertical wiring line and a second vertical wiring line that are buried inside the element body so that end surfaces thereof are exposed from the first main surface of the element body and that are electrically connected to the coil wiring line. In a first cross section that is perpendicular to a direction in which the coil wiring line extends and intersects the first vertical wiring line, a top surface of the coil wiring line contacts a bottom surface of the first vertical wiring line and the top surface of the coil wiring line is substantially shaped like a convex surface.

    Abstract: A coil component: including a first planar spiral wiring and a second planar spiral wiring located above the first planar spiral wiring in a laminated direction and interconnected through connection vias to the first planar spiral wiring. The second planar spiral wiring is wound in a direction different from a winding direction of the first planar spiral wiring when viewed in the laminated direction. The first planar spiral wiring and the second planar spiral wiring have respective innermost circumferential overlapping portions overlapping with each other at the innermost circumferential region when viewed in the laminated direction. At least both end parts of the innermost circumferential overlapping portion of the first planar spiral wiring are in an interconnection with at least both end parts of the innermost circumferential overlapping portion of the second planar spiral wiring through the connection vias.
