Abstract

In an exemplary embodiment, a coil component includes: an element body partthat contains magnetic metal grains and nonmagnetic materials and has insulation property; and a coilembedded in the element body partand formed by a winding conductor. The element body parthas a main partand a low magnetic permeability partwhose relative permeability is lower than that of the main part; the coilhas a first surfaceand a second surfacerespectively representing surfaces positioned on opposite sides in the direction of the coil axis and intersecting the coil axis; and the low magnetic permeability partis provided between a first planeflush with the first surface, and a second planeflush with the second surface, in a manner away from the first planeand the second plane
