1. A magnetic sensor comprising:
a plurality of magnetoresistive elements; and
a plurality of pairs of soft magnetic bodies that shield a magnetic field that is applied to the magnetoresistive elements, wherein
each soft magnetic body includes two pairs of straight sides and at least one sloping side, which is located between two adjacent ones of the straight sides, such that the sloping side is sloped with respect to each of the adjacent ones of the straight sides, as viewed in a film thickness direction of the plurality of magnetoresistive elements,
the magnetoresistive elements has a plurality of groups each including more than one of the magnetoresistive elements, the magnetoresistive elements of each group are arranged in an aligning direction, and the groups are arranged in a direction perpendicular both to the aligning direction and to the film thickness direction, and
each pair of the soft magnetic bodies is arranged to face opposite sides of a corresponding one of the magnetoresistive elements in the film thickness direction and such that the pairs of soft magnetic bodies are arranged in the direction perpendicular both to the aligning direction and to the film thickness direction.
