The present invention provides a method of producing a tetracyanoborate-containing ionic compound in a milder condition more efficiently and less expensively than conventional methods, and a tetracyanoborate-containing ionic compound having a reduced content of impure components. An ionic compound of the present invention is represented by the following general formula (I), has a content of fluorine atom-containing impurities of 3 mol % or less per 100 mol % of the ionic compound, and a method for producing an ionic compound represented by the general formula (I) of the present invention comprises a step of reacting starting materials containing a cyanide and a boron compound. n n(In the formula, Kt m+ denotes an organic cation [Kt b ] m+ or an inorganic cation [Ke] m+ ; and m denotes an integer of 1 to 3.) |
