Abstract
An embodiment provides a coil component including a base body, and a coil conductor provided in the base body. At least partial region of the base body contains (i) a plurality of first metal magnetic particles having a first aspect ratio greater than one and having a first average particle size and (ii) a plurality of second metal magnetic particles having a second aspect ratio greater than the first aspect ratio, having a second average particle size less than the first average particle size. The first and second metal magnetic particles are oriented in a reference direction in the base body.

A coil component comprising:
- a base body;
- and
- a coil conductor provided in the base body;
- wherein the base body has an oriented region containing (i) a plurality of first metal magnetic particles having a first aspect ratio greater than one, having a first average particle size and oriented in a reference direction and (ii) a plurality of second metal magnetic particles having a second aspect ratio greater than the first aspect ratio, having a second average particle size less than the first average particle size and oriented in the reference direction,
- wherein the coil conductor extends around a coil axis,
- wherein the reference direction extends perpendicularly to the coil axis,
- wherein the base body has a first region covering one end surface of the coil conductor in an axial direction extending along the coil axis, and
- wherein the oriented region occupies at least part of the first region.
