Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a measuring method of moisture in a fused salt bath, which can perform even in-line measurement during plating in a simple way.SOLUTION: A moisture measuring method measures moisture in a fused salt bath using a mixed salt of an organic salt and aluminum chloride. An electrode pair which comprises a working electrode and a counter electrode is provided in the fused salt bath. A value of a current which flows between the electrode pair during the application of voltage between the electrode pair is measured, and the current value is converted to moisture content. The conversion of the current value to the moisture content is possible by using a calibration curve obtained in advance.
