Abstract
Reduction of the S/N in an output from a magnetic sensor using the magnetic impedance effect is suppressed. A magnetic sensoris provided with a sensitive elementincluding: plural soft magnetic material layers; and a nonmagnetic amorphous metal layerprovided between the plural soft magnetic material layers, wherein the soft magnetic material layersfacing each other with the nonmagnetic amorphous metal layerinterposed therebetween are antiferromagnetically coupled to sense a magnetic field by a magnetic impedance effect.
