ABSTRACT:
A magnetic sensor includes a plurality of rows of elements in each of which a plurality of magnetoresistive elements are aligned in a direction which intersects at a predetermined angle the passing direction of an object to be detected, the object including magnetic patterns, the plurality of rows of elements being staggered in the passing direction of the object to be detected. Each of the magnetoresistive elements includes a magnetic sensitive region, and each of the magnetoresistive elements in one of the rows of elements is aligned so that the magnetic sensitive region overlaps the magnetic sensitive region of the magnetoresistive element in another row in the passing direction of the object to be detected. Accordingly, the whole region passed by the object in the alignment direction of the magnetoresistive elements is a magnetic sensitive region.
