Abstract
A current detection device includes a plane-shaped first coil pattern having a winding number of at least two or more, a magnetic field detection element isolated from the first coil pattern in a direction orthogonal to a plane of the first coil pattern, and arranged to receive a magnetic field formed by the first coil pattern, a driving circuit configured to drive the magnetic field detection element and output an output signal, a second coil pattern, a first substrate on the first coil pattern, a second substrate on the second coil pattern, and a third substrate on the magnetic field detection element. The magnetic field detection element is provided between the first coil pattern and the second coil pattern.
