Abstract

A magnetic sensor includes a bridge circuit including a first arm and a second arm, a first substrate, and a second substrate. The first arm is provided on the first substrate. The second arm is provided on the second substrate. The first arm includes a first resistor and a second resistor connected in series. The second arm includes a third resistor and a fourth resistor connected in series. The second substrate is located at a position away from the first substrate so that a phase of a resistance of the second arm when a target magnetic field changes periodically is different from that of a resistance of the first arm when the target magnetic field change periodically.
