[Problem] In the GSR sensor element, tm and ti of rising pulse detection are so close that the induced voltage has a considerable magnitude at time tm, and variations due to the magnetic field cannot be ignored. The induced voltage is removed from the output voltage to realize a rising pulse detection type GSR sensor. [Solution] Based on the knowledge that the positive voltage is reversed with respect to the direction of the current flowing in the magnetic wire, the induced current is canceled by providing two magnetic wires in which the current in the opposite positive direction flows in one coil. A voltage proportional to may be detected.
