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.
