Abstract
A magnetic sensor includes a substrate, and a pattern forming region on the substrate, the pattern forming region having a substantially quadrangle shape. The pattern forming region includes a magnetic detection element pattern that includes a plurality of linear parts arranged parallel to each other at a predetermined inclination angle to two sides of the quadrangle shape, and a plurality of turning parts configured to alternately connect both end portions in a longitudinal direction of adjacent linear parts of the plurality of linear parts. The magnetic detection element pattern further includes a first pattern, and a second pattern with a resistance change ratio less than the first pattern. An area of the magnetic detection element pattern is less than an area of the pattern forming region in a plane view.
