A measuring method measuring a resistance of a resistor of a magnetic sensor that includes the resistor is provided. The method includes a step of measuring an output voltage of the magnetic sensor in an AC magnetic field, a step of measuring a first combined resistance of the MR element and the resistor in no magnetic field, a step of measuring a second combined resistance of the MR element and the resistor in a constant magnetic field of which a direction and strength are substantially the same as a magnetic field, a step of measuring a third combined resistance of the MR element and the resistor in another constant magnetic field of which a direction and strength are substantially the same as another magnetic field, and a step of calculating the resistance of the resistor based on the output voltage, the first, second and third combined resistance. |
