Abstract
A magnetic sensor includes: at least one sensitive element including a soft magnetic material and having a longitudinal direction and a transverse direction and a uniaxial magnetic anisotropy in a direction intersecting the longitudinal direction, the at least one sensitive element being configured to sense a magnetic field by a magnetic impedance effect; at least one protruding portion including a soft magnetic material and protruding in the longitudinal direction from a longitudinal end of the at least one sensitive element; and a guiding member disposed opposite the at least one protruding portion and made of a soft magnetic material, the guiding member being configured to guide magnetic field lines toward the at least one protruding portion.

A magnetic sensor comprising:
- at least one sensitive element including a soft magnetic material and having a longitudinal direction and a transverse direction and a uniaxial magnetic anisotropy in a direction intersecting the longitudinal direction, the at least one sensitive element being configured to sense a magnetic field by a magnetic impedance effect;
- at least one protruding portion including a soft magnetic material and protruding in the longitudinal direction from a longitudinal end of the at least one sensitive element;
- and
- a guiding member disposed opposite the at least one protruding portion and made of a soft magnetic material, the guiding member being configured to guide magnetic field lines toward the at least one protruding portion,
- wherein the guiding member is disposed to overlap the at least one protruding portion or the guiding member is in contact with a longitudinal end of the at least one protruding portion.
