Abstract
The magnetic sensor can prevent an increase of a positional detection error of a subject/object even in the case of applying an external magnetic field with a magnetic field intensity exceeding a predetermined range. A magnetic sensor is equipped with a magnetoresistive effect element (MR element)that can detect an external magnetic field and a soft magnetic body shield. The soft magnetic body shield(s)are/is positioned above and/or below the MR elementin a side view, and the size of the MR elementis physically included within a perimeter of the soft magnetic body shield
