Abstract
A coil device includes a first conductor on a first layer and arranged in a first spiral shape, a second conductor on a second layer and arranged in a second spiral shape, a transition that connects the first conductor and the second conductor in series, a first terminal connected to an end of the first conductor, and a second terminal connected to an end of the second conductor. The first terminal and the second terminal are outside of the first conductor and the second conductor when viewed in plan. The first conductor and the second conductor each include a plurality of in-plane traces connected in parallel with each other.
