Abstract

A magnetic sensor includes: a first current line, a second current line and a third current line that are disposed in parallel to each other in sequence in a width direction and electrically connected in series; and a magnetoresistive effect element disposed under the second current line and extending along a direction of extension of the second current line, the magnetoresistive effect element having an electric resistance that changes by an induced magnetic field generated by current flowing through the first current line, the second current line and the third current line, the following inequality expression (1) being satisfied:≤5  (1)where Lis a length from an outside of the first current line to an outside of the third current line in a width direction, and Wis a length in the width direction of the magnetoresistive effect element.
