Abstract: A magnetic sensor including a first magneto resistive effect element located on a first surface of a substrate and having a sensitivity axis in a first direction that is one of in-plane directions of the first surface, a positioning soft magnetic body including a first most proximal portion of which a relative position with respect to the magneto resistive effect element is defined, and provided in a non-contact manner with respect to the first magneto resistive effect element, and a first soft magnetic body and a second soft magnetic body juxtaposed in the first direction and extending in a direction away from the first surface, and each of the first soft magnetic body and the second soft magnetic body is magnetically connected to the positioning soft magnetic body.
