Abstract
It is aimed at improving sensitivity of a magnetic sensor using the magnetic impedance effect. A magnetic sensor includes: a non-magnetic substrate; and a sensitive element including a soft magnetic material layer composed of an amorphous alloy with an initial magnetic permeability of 5,000 or more, the soft magnetic material layer being provided on the substrate, having a longitudinal direction and a short direction, being provided with uniaxial magnetic anisotropy in a direction crossing the longitudinal direction, and sensing a magnetic field by a magnetic impedance effect.
