Abstract: A magnetic sensor comprising: an application specific integrated circuit (ASIC); an insulating protective film formed on a surface of the ASIC; a substrate film formed on the insulating protective film; and a magnetic field detection element formed on the substrate film, the magnetic field detection element including two magnetic wires on the substrate film, a detection coil surrounding the two magnetic wires, two electrodes coupled to the two magnetic wires for wire energization, and two electrodes coupled to the coil for coil voltage detection.

Abstract: In a GSR sensor element, tm and ti of rising pulse detection are close, and the induced voltage is significantly high at tm. Thus, a variation due to the magnetic field cannot be ignored. To remove an induced voltage from an output voltage and achieve a GSR sensor with a rising pulse detection system. On the basis of the knowledge that the polarity of an induced voltage becomes opposite relative to a direction of the current flowing in a magnetic wire, if one coil includes therein two magnetic wires in which currents of opposite polarities flow, an induced current is cancelled, allowing for the detection of a voltage in proportion to a magnetic field.
