A process for producing an amine borane compound, comprising the steps of: reacting an amine salt with sodium borohydride in an organic solvent, distilling off the organic solvent to thereby obtain a distillation residue, adding an aqueous alkali hydroxide solution to the distillation residue to thereby form an organic phase and a water phase, fractionating the organic phase, and distilling off the organic solvent from the organic phase. This process is advantageous in terms of cost and ensures safe work environment because the aqueous alkali hydroxide solution is used in place of an organic solvent in the purification (recrystallization) of the amine borane compound. Moreover, the decomposition of the amine borane compound is suppressed by the addition of the aqueous alkali hydroxide solution.
