Abstract: A coil component that includes a coil having a thick coil core and good inductance characteristics and is able to narrow the pitch of a coil electrode is provided. The wiring of a coil electrode in a direction across the direction of a winding axis of the coil electrode includes a plurality of first metal pins and a plurality of second metal pins. By elongating each metal pin, the wiring of the coil electrode is easily elongated in a metal pin direction. Thus, a coil core is easily thickened in the metal pin direction. The wiring of the coil electrode can be formed in the metal pin direction only by arranging the metal pins. Thus, it is possible to provide a coil component that includes a coil having the thick coil core and good inductance characteristics and is able to narrow the pitch of the coil electrode.
