Magnetic sensor and magnetic sensor system

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 includes one or more yokes each formed of a magnetic material,
• each of the one or more yokes 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.
