Abstract
In a magnetic sensor using a magnetic impedance effect, sensitivity is improved as compared to the case where a width of a sensitive element in the short direction is equal from one end to the other end in the longitudinal direction. The magnetic sensor includes: a non-magnetic substrate; and a sensitive element that is provided on the substrate, composed of a soft magnetic material, having a longitudinal direction and a short direction, provided with uniaxial magnetic anisotropy in a direction crossing the longitudinal direction, having a width at a center portion in the longitudinal direction that is smaller compared to a width at each of both end portions in the longitudinal direction, and sensing a magnetic field by a magnetic impedance effect.
