Abstract:
A coil component includes: a magnetic body part and a cover part covering one side of a magnetic layer part; and a coil part embedded in the magnetic body part. The magnetic body part is comprised of the following two types of layers: (A) an oblate soft magnetic grain-containing layer, and (B) a spherical grain-containing layer, wherein layer (A) extends over the entire range of the magnetic body part except for a portion including the coil part in a direction perpendicular to an axis direction of the coil part, layer (B) adjoins layer (A) in the axis direction. The cover part is constituted by multiple layers including one or more of layer(s) (A) and one or more of layer(s) (B) and extending over the entire range of the magnetic body part in the direction perpendicular to the axis direction.
