Abstract: A magnetic sensor includes: plural sensitive elements 31 each including a soft magnetic material layer 105 having a longitudinal direction and a transverse direction and a conductor layer having higher conductivity than the soft magnetic material layer 105 and extending through the soft magnetic material layer 105 in a longitudinal direction, the sensitive element 31 having uniaxial magnetic anisotropy in a direction intersecting the longitudinal direction and being configured to sense a magnetic field by a magnetic impedance effect; and a connecting portion 32 continuous with the conductor layer of the sensitive element and configured to connect transversely adjacent sensitive elements 31 in series.

Abstract: A magnetic sensor includes: a non-magnetic substrate; and a sensitive element 31 having a longitudinal direction and a short direction, provided with uniaxial magnetic anisotropy in a direction crossing the longitudinal direction, and sensing a magnetic field by a magnetic impedance effect, wherein the sensitive element 31 includes plural soft magnetic material layers 105a to 105d and plural non-magnetic material layers 106a to 106c configured with a non-magnetic material and laminated between the plural soft magnetic material layers 105a to 105d, and the soft magnetic material layers 105a to 105d facing each other with each of the non-magnetic material layers 106a to 106c interposed therebetween are antiferromagnetically coupled.
