Claim 0:
1. A magnetic sensor comprising:
a magnetic field converter;
a magnetic field detector; and
a plurality of shields separated from each other, each of the plurality of shields being formed of a soft magnetic material, wherein
the magnetic field converter is formed of a soft magnetic material, and is configured to receive an input magnetic field for the magnetic sensor and to output an output magnetic field,
the magnetic field detector generates a detection signal dependent on the output magnetic field,
the magnetic field detector includes one or more magnetic detection elements,
each of the one or more magnetic detection elements is configured to receive the output magnetic field and to generate a detection value which varies depending on the output magnetic field,
the detection signal depends on the detection value,
as viewed in a direction parallel to a first direction, the plurality of shields are aligned in a second direction intersecting the first direction and overlap the magnetic field converter and the magnetic field detector, and
as viewed in a direction parallel to the first direction, each of the plurality of shields has such a shape that its maximum dimension in the second direction is smaller than its maximum dimension in a third direction intersecting each of the first direction and the second direction, and as viewed in a direction parallel to the third direction, each of the plurality of shields has such a shape that its maximum dimension in the first direction is smaller than its maximum dimension in the second direction.
