PROBLEM TO BE SOLVED: To provide a magnetic sensor capable of detecting magnetic variations with high sensitivity and high precision, while preventing unwanted signal component that causes noise from occurring, due to parallel arrangement of magnetic impedance sensors. SOLUTION: A magnetic sensor provided with a plurality of magnetic impedance sensors has frequency signal terminals, with which the magnetic impedance sensors supply or acquire frequency information. The frequency signal terminals are connected via wires, whereby the frequencies of pulses, or the like, to be applied to the respective magnetic impedance elements of the plurality of magnetic impedance sensors are all made equal.
