1. A coil component comprising a body and a coil conductor embedded in the body,
wherein
the body includes a magnetic layer and a non-magnetic layer,
the magnetic layer is made of a composite material including a metal particle and a resin material,
the non-magnetic layer is arranged neither to penetrate through a winding portion of the coil conductor nor to entirely penetrate through the body,
a coil configured by the coil conductor has an end surface in an axis direction of the coil,
the non-magnetic layer has a surface that covers a winding core portion of the coil conductor when viewed in the axis direction of the coil and is flush with the end surface of the coil, and
the coil is configured such that no non-magnetic layer is sandwiched between the coil conductors in the axis direction of the coil.
