PROBLEM TO BE SOLVED: To provide an impedance measuring device that does not require a complicated tuning operation.SOLUTION: A measurement auxiliary circuit 11 is constituted so as to form a resonance circuit 12 together with an object 2. An ATAC 10 is coupling to the resonance circuit 12. A signal generator 13 applies an AC probe signal Vto the resonance circuit 12. An impedance detection unit 16 measures a voltage of at least one node and/or a current of at least one path in a state where an impedance measuring device 1 is stable, and detects an impedance of the object 2 on the basis of a measurement value. |
