Abstract: An antenna element includes a multilayer body and a coil conductor. The multilayer body includes a first non-magnetic portion and a first magnetic portion laminated together. The first magnetic portion is closer to a first principal surface than is the first non-magnetic portion. The coil conductor includes a first conductor pattern portion and a first insulating pattern portion. The first conductor pattern portion is disposed between the first non-magnetic portion and the first magnetic portion. The first insulating pattern portion is provided on the first conductor pattern portion at a side facing the second principal surface, and has a line width less than a line width of the first conductor pattern portion. The first insulating pattern portion overlaps the first conductor pattern portion in plan view as viewed in a lamination direction of the multilayer body.

Abstract: A coil device includes a device body and terminal electrodes. Coils are provided in the device body. The device body has a laminated structure including insulating layers, and includes a mounting surface orthogonal to the laminating direction of the insulating layers. The terminal electrodes are located on the mounting surface. An entirety of the terminal electrodes overlaps a coil opening of the coils when viewed in the laminating direction.
