Current detection device
A current detection device includes a first coil, a magnetic field detection element, a shield layer, a second coil, and an operation circuit. The first coil has a planar shape. The magnetic field detection element is disposed in a spaced apart manner from the first coil in a direction orthogonal to a plane of the first coil, and is disposed so as to receive a magnetic field which the first coil generates. The shield layer is disposed between the first coil and the magnetic field detection element. The second coil is disposed in a spaced apart manner from the first coil with respect to an axis perpendicular to the shield layer. The operation circuit operates the second coil.
