Abstract
A magnetic sensor includes a magnetic detection element circuit that includes first and second magnetic detection elements, which are connected in series, and an output terminal, which is positioned between the first and second magnetic detection elements; an impedance matching device, which has a prescribed input voltage range and is connected to an output terminal of the magnetic detection element circuit; a first current supply source, which supplies an electric current to the magnetic detection element circuit; and a second current supply source, which supplies an electric current to the impedance matching device. A resistor is provided between the output terminal of the magnetic detection element circuit and the first current supply source and/or a reference electric potential point.
