Abstract
A magnetic field detecting device which comprises a magnetic impedance sensor including a magnetic impedance elementin which a detecting coilwound around an amorphous wirefor detecting and outputting the external magnetic field around the amorphous wire at a rise time and a fall time of the pulse current in case of the pulse current is applied to the amorphous wire and a signal processing deviceincludes two sample-hold circuitfor respectively sample-holding the alternate current damped oscillation voltage at the rise time and the fall time of the applied pulse current, wherein the output signal in response to the external magnetic field around the amorphous wire is output based on the detected two alternate current damped oscillation voltages output at the rise time and the fall time of the pulse current.
