Abstract
A magnetic sensor of the present invention has an elongate element portion having a magnetoresistive effect and a pair of elongate soft magnetic bodies that are arranged along the element portion on both sides of the element portion with regard to a short axis thereof. Each soft magnetic body includes a central portion that is adjacent to the element portion from one end to another end of the element portion with regard to a long axis direction thereof and a pair of end portions that protrude from the central portion in the long axis direction. A width of at least one of the end portions gradually decreases in a direction away from the central portion in at least a part of the end portions in the long axis direction thereof.
