Abstract
In a multilayer coil component, a coil is configured by electrically connecting coil conductors respectively provided in magnetic body layers constituting an element body and metal magnetic particles have a normal particle having an ellipsoidal shape and flat particles having an ellipsoidal shape flatter in a thickness direction than the normal particle. A plurality of the normal particles and at least one of the flat particles disposed such that a surface (reference surface) including a major axis direction orthogonal to the thickness direction and a minor axis direction is along the forming surface of the coil conductor in the magnetic body layer are arranged in the lamination direction of the magnetic body layers between the coil conductors.
