Abstract: The present invention relates to a method for producing a lithium halide compound, capable of industrially advantageously producing a lithium halide compound having a low water content, particularly lithium bromide and lithium iodide, at a high reaction efficiency without accompanying a step of directly removing water, and the method including mixing lithium sulfide, a halogen molecule of at least one of bromine and iodine, and a first solvent; and removing the first solvent, wherein the first solvent is a solvent that dissolves a lithium halide containing the same halogen element as the halogen molecule.
