Abstract
Disclosed herein is a coil component that includes an element body made of a first magnetic material, a coil conductor embedded in the element body, and first and second magnetic films made of a second magnetic material having higher permeability than that of the first magnetic material. The element body has an upper surface crossing a coil axis of the coil conductor and first and second side surfaces extending substantially parallel to the coil axis. The first magnetic film is formed on the upper surface and first side surface of the element body, and the second magnetic film is formed on the upper surface and second side surface of the element body.
