1. A device of manufacturing lithium sulfate comprising:
a reaction body in which a reaction of lithium phosphate and sulfuric acid is performed, the reaction body being divided into an upper space and a lower space;
a pressurizer for applying pressure to the inside of the reaction body;
a stirrer disposed in the upper space for stirring the lithium phosphate and sulfuric acid to produce a mixture containing lithium sulfate and phosphoric acid; and
a filter disposed inside the reaction body and separating the filtrate containing the phosphoric acid into the lower space by filtering the mixture.
