Abstract
A superconducting current measuring circuit is provided with a detection loop through which a current flows by the influence of a magnetic field generated by a measurement target current. The detection loop contains a superconductor. The superconducting current measuring circuit is also provided with a superconducting sampler circuit for measuring the current flowing through the detection loop.
