PROBLEM TO BE SOLVED: To provide a magnetic flux meter capable of measuring the absolute value of a magnetic flux with a simple structure and high sensitivity. ! SOLUTION: A magnetic flux meter 1 includes a plurality of SQUIDs 8 having two Josephson junctions 10 in a superconductivity loop 9. The plurality of SQUIDs 8 are connected so as to be electrically in parallel with each other. The length of the current path of the superconductivity loop 9 between the Josephson junctions 10 of at least one SQUID 8 among the plurality of SQUIDs 8 is different from the length of the current path of the superconductivity loop 9 between the Josephson junctions 10 of any other SQUIDs 8. !
