Claim:
1. A process for producing a fluorine-containing complex salt comprising the step of triggering a reaction on a reaction mother liquor containing a plurality of cation species and a fluoroanion in a state that they have been dissolved in a solvent, wherein triggering the reaction applies energy to the reaction mother liquor, changes acidity of the reaction mother liquor, or both, thereby accelerating decomposition of the fluoroanion and precipitating a complex salt containing a plurality of cation species and fluorine, as a solid, from the reaction mother liquor, wherein the fluoroanion has an A-F bond, wherein A is at least one element selected from the group consisting of Al, Ti, B, Si, P, S, As, Se, Sb and Te.
