Abstract:
1. A magnetic sensor comprising: a single substrate; and a plurality of element groups, each element group including a pair of magnetoresistive elements which are identical in terms of magnetization direction of a pinned layer, wherein each of said plurality of element groups disposed at an upper portion of said substrate in such a way that the magnetization direction of said pinned layer of each element group is substantially parallel to a direction in which a distance from a centroid of said substrate increases, and such that said pair of magnetoresistive elements are disposed adjacent to each other in the direction in which the distance from the centroid of said substrate increases such that one of the magnetoresistive elements of the pair is disposed toward the center of the centroid of the substrate and the other is disposed toward the edge of the substrate.
