Abstract
A surface-mount inductor includes an element assembly having a core, a coil, and a magnetic material; and a pair of external terminals on a mounting surface of the element assembly. The core has a base portion and a columnar portion on an upper surface of the base portion. The coil is disposed on the base portion, and has a wound portion on the columnar portion, and a pair of extended portions extended from the wound portion. In a cross-section parallel to a winding axis, the wound portion has, in at least a part of a region where the upper stage and the lower stage are in contact with or oppose each other, a boundary surface formed by one portion of a conductive wire at one of upper and lower stage sides being in contact with or opposing a plurality of portions of the conductive wire at the other side.
