Abstract

A magnetic sensor (1) includes a plurality of magnetoresistive elements (S1-S4) that are formed by stacking a magnetic layer (61) and a non-magnetic layer (62) on a substrate and that exhibit a magnetoresistive effect and a soft magnetic member (3) 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 (3a, 3b) respectively extending in an X1-X2 direction and a Y1-Y2 direction, combined together in the shape of a lattice. The magnetoresistive elements (S1-S4) have a sensitivity direction in the Y2 direction and include a magnetoresistive element (S1, S4) located on a Y1 side portion side of the first soft magnetic portion and a magnetoresistive element (S2, S3) 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.
