PROBLEM TO BE SOLVED: To provide a high-sensitivity frequency modulated magnetic sensor with a miniaturized magnetic head. SOLUTION: In the magnetic sensor, having two CMOS inverters 1 and 2, an amorphous wire 5 connected in series to a resistor 4, and a multi-vibrator oscillation circuit A consisting of capacitance C(3), it is set so that the supply voltage is≤3V, and the series resistance of a resistor R(4) and the amorphous wire 5 is≤500Ω. The time width when the input voltage of the two CMOS inverters 1 and 2 is kept at a threshold voltage is varied by an externally applied magnetic field. COPYRIGHT: (C)2004,JPO
