Abstract
An object of the present invention is to provide a magnetic sensor less subject to an environmental magnetic field. A magnetic sensor includes magnetic detection elements MRto MRpositioned on a first plane Pand a magnetic memberA provided on a second plane P. The magnetic memberA includes first and second leg partsandand a first main body partpositioned between the first and second leg partsandso as to form a first spacebetween itself and the second plane P. The magnetic detection elements MRto MRare covered with the first main body part. According to the present invention, magnetic field to be detected is collected to the first and second leg partsand, and the magnetic detection elements MRto MRare covered with the first main body part, thereby allowing an environmental magnetic field acting as noise to bypass the magnetic detection elements MRto MRthrough the first main body part. Thus, influence of the environmental magnetic field can be reduced.
