A device for manufacturing lithium carbonate is provided. According to the present invention, the device for manufacturing the lithium carbonate comprises: a reaction container containing a lithium hydroxide solution and carrying out a reaction under atmospheric pressure; a lithium hydroxide solution supply pipe connected to the reaction container; an atmospheric carbon dioxide storage tank connected to the reaction container to supply atmospheric carbon dioxide gas to the reaction container; and a stirrer installed in the reaction container and stirring the lithium hydroxide solution so that lithium carbonate generated by the reaction of the lithium hydroxide solution and carbonic acid gas is not adhered to the wall surface of the reaction container. In a gas phase carbonation method using carbon dioxide gas, an agitation or injection method of a high pressure environment is improved and the vapor carbonization and the wall adhesion in an atmospheric pressure environment is prevented, thereby improving the production yield of lithium carbonate. 탄산리튬 제조 장치를 제공한다. 본 발명에 따르면, 수산화리튬 용액을 수용하며, 상압하에서 반응이 이루어지는 반응용기, 상기 반응용기에 연결되는 수산화리튬 용액 공급관, 상기 반응용기에 연결되어 상기 반응용기로 상압 탄산가스를 공급하는 상압 탄산가스 저장 탱크, 및 상기 반응용기 내에 설치되고, 상기 수산화리튬 용액과 상기 탄산가스의 반응으로 생성된 탄산리튬이 상기 반응용기의 벽면에 부착되지 않도록 상기 수산화리튬 용액을 교반하는 교반기를 포함한다.
