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.
