Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A magnetic sensor, comprising: a magnetoresistive element that is formed by stacking a magnetic layer and a non-magnetic layer on a substrate and that exhibits a magnetoresistive effect; and a soft magnetic member that converts a vertical magnetic field component input from the outside from a direction perpendicular to the substrate into a horizontal magnetic field component in a direction along the substrate and that provides the horizontal magnetic field…
