Abstract
An object of the present invention is to provide a magnetic sensor having enhanced magnetic detection sensitivity by bending magnetic flux more largely. A magnetic sensor includes magnetic detection elements MRand MRpositioned on a plane P separating a first space Sand a second space S, a first magnetic memberdisposed in the first space Sso as to be between the magnetic detection elements MRand MRwhen viewed in the z-direction, and a second magnetic memberdisposed in the second space S. The magnetic detection element MRis positioned between the first magnetic memberand a first partof the second magnetic memberwhen viewed in the z-direction. The magnetic detection element MRis positioned between the first magnetic memberand a second partof the second magnetic memberwhen viewed in the z-direction. According to the present invention, magnetic flux collected by the first magnetic member is attracted to the first and second parts of the second magnetic member, allowing the magnetic flux to be bent more largely. Thus, the magnetic detection sensitivity of the magnetic sensor can be enhanced.
