Abstract
A surface-mounting-type coil component includes a wound coil, a box-shaped core member, and a core member defining a cover. At two ends of the coil, two extending portions are extended in opposite directions so as to be separated by 180 degrees along a straight line passing through the center of the wound coil. The box-shaped core member includes a recess for accommodating the coil therein. The four corners of the box-shaped core member have been removed. Grooves are formed in a side wall defining the recess at 90 degree intervals. Portions of the two extending portions are accommodated in the grooves, with one end of each extending portion being disposed at a mounting surface of the box-shaped core member so as to be extended outwardly.
