Claim:
1. A magnetic field sensing module, comprising: a plurality of magnetic flux concentrators, wherein each of the magnetic flux concentrators extends along a first direction, and the magnetic flux concentrators are arranged along a second direction; and a plurality of sensing elements, respectively disposed in a position corresponding to a position between the magnetic flux concentrators and positions corresponding to two sides, arranged along the second direction, of the magnetic flux concentrators, wherein the sensing elements disposed in the positions corresponding to the two sides arranged along the second direction are disposed on two opposite sides of a reference plane with a space apart, and the sensing elements disposed on the two opposite sides of the reference plane are spaced apart from each other along the first direction, wherein the reference plane passes through a central region of the magnetic flux concentrators, the reference plane is substantially perpendicular to the first direction, and sensing directions of the sensing elements are substantially the same.
