Abstract
A current detection apparatus of an embodiment includes a coil pattern, a magnetic field detection element and a shielding layer. The coil pattern is configured with an arc-shaped planar coil and straight line portions parallel to each other extending from an end portion of the arc-shaped planar coil. The magnetic field detection element is arranged away from the coil pattern in a direction orthogonal to a plane of the planar coil and disposed to receive a magnetic field in a first direction generated by the coil pattern. The shielding layer is provided between the coil pattern and the magnetic field detection element and is provided with a slit portion.
