Abstract
A magnetic sensor comprises a magnetic material portion; an excitation portion; and a magnetic detection portion, the magnetic sensor detecting a magnetic field by the magnetic detection portion detecting a detection magnetic field generated due to magnetic moments of the magnetic material portion. The excitation portion is configured to include a conductive material formed into an elongated shape, the magnetic material portion is a soft magnetic film formed on a surface of the conductive material, and the magnetic moments of the magnetic material portion are oriented along circumferential directions of the conductive material orthogonal to a longitudinal direction of the conductive material such that the magnetic moments directed to one of the circumferential directions and the magnetic moments direction in another circumferential direction opposite to the one circumferential direction are distributed in substantially equal amounts.
