| Zusammenfassung: | 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. |
