Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing low-moisture lithium hexafluorophosphate, which method is effective with no need of a special post-treatment and the like. SOLUTION: An anhydrous hydrogen fluoride solution of lithium fluoride, or a solution in which lithium fluoride is dissolved in a filtrate circulatingly used in a process of manufacturing lithium hexafluorophosphate is fluorinated before or after the lithium fluoride in the solution is reacted with phosphorus pentafluoride.
