Abstract
The size and cost of a magnetic sensor suitable for closed loop control is reduced. A magnetic sensor includes a magnetoresistive effect element that is electrically connected between terminals and extends in the x-direction and a magnetic member that is electrically connected between the terminals and extends in the x-direction along the magnetoresistive effect element. The magnetoresistive effect element is disposed offset with respect to the center position of the magnetic member in the y-direction. Magnetic flux to be detected is collected by a magnetic member and current is made to flow in the magnetic member in accordance with the resistance value of the magnetoresistive effect element, achieving closed loop control. The magnetic member functions both as a magnetism collection function and as a cancel coil, which reduces the number of elements required, and which also achieves a reduction in size and cost.
