A magnetic sensor having a wide magnetic field range is provided. A magnetic sensor is providing. The magnetic sensor includes: a substrate; a magnetic converging part that is arranged on the substrate or in the substrate; a plurality of magnetic detecting parts; and a calculating part, wherein the magnetic converging part converts, at each magnetic detecting part among the plurality of magnetic detecting parts, an external magnetic field oriented in a direction different from the magnetically sensitive-axis direction to a magnetic field oriented in the magnetically sensitive-axis direction, the each magnetic detecting part includes a plurality of magneto-resistance elements arrayed parallel with the plane of the substrate, each magneto-resistance element among the plurality of magneto-resistance elements includes a laminated-layer structure formed of: a free layer in which a magnetization direction is changed by the external magnetic field; a pinned layer with fixed magnetization; and a spacer layer provided between the free layer and the pinned layer, a longitudinal direction of the free layer of one magneto-resistance element included in the plurality of magneto-resistance elements coincides with a longitudinal direction of the free layer of at least one magneto-resistance element adjacent to the one magneto-resistance element, and the at least one magneto-resistance element adjacent to the one magneto-resistance element is arrayed in the longitudinal direction of the free layer of the one magneto-resistance element.
