Abstract: A coil component includes a magnetic body part and a coil part. The magnetic body part has first and second magnetic layers stacked together alternately in one axis direction, and cover parts covering the first and second magnetic layers from the one axis direction. The coil part has conductor patterns provided on the second magnetic layers. The magnetic body part includes: oblate soft magnetic grain-containing layers extending over the entire range of the magnetic body part in the direction perpendicular to the one axis direction, exposed in the direction perpendicular to the one axis direction, and formed by oblate soft magnetic grains whose thickness direction is oriented in the one axis direction; and spherical grain-containing layers adjoining the oblate soft magnetic grain-containing layers in the one axis direction, and formed by insulative spherical grains.

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.
