Abstract: Disclosed herein is a coil component that includes: a first core having a mounting surface and a coil placing surface positioned opposite to the mounting surface; a lower coil placed on the coil placing surface such that a coil axis of the lower coil extends substantially perpendicular to the coil placing surface, the lower coil having one end drawn to a first area of the mounting surface and other end drawn to a second area of the mounting surface; and an upper coil substantially coaxially stacked on the lower coil, the upper coil having one end drawn to a third area of the mounting surface and other end drawn to a fourth area of the mounting surface. The lower coil is greater in a coil diameter than the upper coil.
