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.
Abstract translation: Z方向的磁场分量由磁场引导层引导，并且与X射线方向的磁敏感元件的灵敏度轴方向相同，得到检测输出。 桥式电路形成有多个磁传感器，并且被配置为使得不向X方向的磁场分量提供输出。 然而，当将X方向的外部磁场吸引到磁场引导层时，可能会发生X方向的灵敏度的变化。 因此，磁场引导层的第一部分的软磁特性劣化，从而降低第一部分的磁导率。

Abstract: A magnetic sensor includes a plurality of magnetoresistive elements that are formed by stacking a magnetic layer and a non-magnetic layer on a substrate and that exhibit a magnetoresistive effect and a soft magnetic member that converts a vertical magnetic field component into a horizontal magnetic field component. The soft magnetic member is formed of a plurality of first and second soft magnetic portions respectively extending in an X1-X2 direction and a Y1-Y2 direction, combined together in the shape of a lattice. The magnetoresistive elements have a sensitivity direction in the Y2 direction and include a magnetoresistive element located on a Y1 side portion side of the first soft magnetic portion and a magnetoresistive element located on a Y2 side portion side of the first soft magnetic portion, respectively receiving horizontal magnetic field components from the Y1 direction and Y2 direction.
