Abstract: A magnetic field component in a Z direction is guided by a magnetic field guide layer and applied to a magnetic sensor in an X direction that is the same as a sensitivity axis direction thereof, and a detection output is obtained. A bridge circuit is formed with a plurality of magnetic sensors and configured such that an output is not provided for a magnetic field component in the X direction. However, when an external magnetic field in the X direction is drawn to the magnetic field guide layer, variation of sensitivity for the X direction may occur. Thus, soft magnetic characteristics of a first portion of the magnetic field guide layer are deteriorated to decrease the magnetic permeability of the first portion.
