Abstract

A magnetic sensor circuit includes: a first element including series-connected resistor and capacitor, or including only a capacitor; a second element including series-connected resistor and inductor, or including a magnetic sensor sensing a magnetic field by a magnetic impedance effect; a third element including series-connected resistor and capacitor, or including only a capacitor; and a fourth element including a magnetic sensor sensing a magnetic field by a magnetic impedance effect, wherein a first series circuit part including the series-connected first and second elements and a second series circuit part including the series-connected third and fourth elements are connected in parallel, and, when the magnetic field sensed by the magnetic sensor has a predetermined reference value, a product of impedance Z1 of the first element and impedance Z4 of the fourth element and a product of impedance Z2 of the second element and impedance Z3 of the third element are equal.
