Abstract

See full text

A magnetic coupling coil element in one embodiment includes a magnetic base body that includes an intermediate magnetic layer, a first magnetic layer disposed over the intermediate magnetic layer, and a second magnetic layer disposed under the intermediate magnetic layer; a first coil conductor provided in the first magnetic layer; and a second coil conductor provided in the second magnetic layer. The intermediate magnetic layer has a saturation magnetic flux density lower than saturation magnetic flux densities of the first magnetic layer and the second magnetic layer in a first region that overlaps with the first coil conductor and the second coil conductor in plan view.
