Abstract

A coil component according to one aspect of the present invention includes: a coil conductor extending around a coil axis; and a magnetic base body intersecting the coil axis. The magnetic base body includes first metal magnetic particles, second metal magnetic particles, and magnetic gap portions, each of the first metal magnetic particles having a first elastic limit and a first relative permeability, each of the second metal magnetic particles having a second elastic limit smaller than the first elastic limit and a second relative permeability lower than the first relative permeability, each of the magnetic gap portions covering a surface of associated one of the first metal magnetic particles and configured such that a first thickness of the magnetic gap portion in a first direction along the coil axis is larger than a second thickness of the magnetic gap portion in a second direction perpendicular to the first direction.
