Abstract
In a magnetic sensor having soft magnetic metallic elements disposed in opposite sides of a bridge circuit for sensing an external magnetic field by using a phenomenon where a skin depth of the soft magnetic metallic elements changes in dependence on a strength of the external magnetic field, each of the soft magnetic metallic elements is formed in a zigzag shape having parallel sections extending in a direction of the external magnetic field. The soft magnetic metallic element may have a multi-layer structure where soft magnetic layers are laminated with a non-magnetic insulator layer interposed therebetween.
