    • PROBLEM TO BE SOLVED: To provide a noncontact measurement method noncontact-measuring current flowing through a plurality of superconducting wires constituting parallel wires using hole sensors and confirming the generation of current nonuniformity between the parallel wires.
      SOLUTION: The noncontact measurement method of current flowing through the plurality of superconducting wires connected in parallel includes a step of disposing a plurality of hole sensors; a step of setting a voltage value measured by each hole sensor and a matrix relational expression to define the relation between a current value flowing through each superconducting wire and the voltage value; a step of measuring a measured voltage value by applying a set current value by two or more times to the plurality of superconducting wires through the plurality of hole sensors; a step of computing a value of each variable of the variable matrix by substituting the set current value and the measured voltage value; and a step of computing a plurality of unknown voltage values measured by the plurality of hole sensors under the condition where an unknown current flows through each superconducting wire and the intensity of the unknown current flowing through each superconducting wire.
