Provided is a method for producing difluorophosphate which is characterized by obtaining the difluorophosphate by reacting at least one salt, as a raw material, selected from a halide salt, a carbonate, a phosphate, a hydroxide and an oxide of an alkali metal, an alkali earth metal or an onium with a difluorophosphoric acid in the difluorophosphoric acid, then separating a precipitate from the difluorophosphoric acid by solid liquid separation, the precipitate being precipitated by crystallization operation in the difluorophosphoric acid, and distilling the difluorophosphoric acid contained in the precipitate. |
