Abstract
A magnetic sensor includes a magnetoresistance effect element and a hard bias layer. The magnetoresistance effect element is configured to have a striped form which has a sensitivity axis in a predetermined direction, and configured to have a structure in which a free magnetic layer, in which magnetization varies with respect to an external magnetic field, a non-magnetic layer, and a fixed magnetic layer, in which the magnetization is fixed, are laminated. The hard bias layer is disposed in a longitudinal direction of the striped form, disposed outside of the magnetoresistance effect element to be separated from the magnetoresistance effect element.
