Magnetic balance type current sensor
A magnetic balance type current sensor includes a magnetic balance type current sensor including a magnetoresistance effect element whose characteristic changes owing to an induction magnetic field from a current to be measured flowing through a conductor, a feedback coil configured to be disposed in the vicinity of the magnetoresistance effect element and generate a cancelling magnetic field cancelling out the induction magnetic field, a magnetic shield configured to attenuate the induction magnetic field and enhance the cancelling magnetic field, and a hard bias layer configured to be provided on or above the magnetic shield.
