Abstract
A coil component includes an insulating layer in which a magnetic core is embedded, coil electrodes wound around the magnetic core, external connection pad electrodes that are provided on the upper surface of the insulating layer and are connected to the coil electrodes. Each of the coil electrodes includes a plurality of inner metal pins standing in the insulating layer, a plurality of outer metal pins standing in the insulating layer, a plurality of upper wiring patterns formed on the upper surface of the insulating layer, and a plurality of lower wiring pattern formed on the undersurface of the insulating layer. Each of the pad electrodes is directly connected to the upper end surface of the inner metal pin or the outer metal pin, and has, in plan view, an area larger than that of the single upper wiring pattern or the single lower wiring pattern.
