To provide methods and devices capable of efficiently culturing microalgae while suppressing diffusion of carbon dioxide to the atmosphere.SOLUTION: A method for culturing microalgae and a culture device 1 are disclosed. The culture method comprises a step of removing microalgae from a culture fluid S to obtain a separated solution; and a step of contacting the separated solution to a carbonate substance to obtain a solution W; and a step contacting the solution W to the culture fluid S to supply carbon source to the culture fluid S. The culture device 1 comprises: a culture vessel 10 for containing a culture fluid S; separation means 20 for obtaining a separated solution by removing the microalgae from the culture fluid S; dissolving means 30 for dissolving a carbonate substance into the separated solution to obtain a solution W; and means 40 for supplying carbon source to the culture fluid S by contacting the solution W and the culture fluid S.SELECTED DRAWING: Figure 1 【課題】大気への二酸化炭素の拡散を抑制しつつ、効率よく微細藻類を培養できる微細藻類の培養方法及び微細藻類の培養装置の提供。【解決手段】微細藻類の培養方法及び培養装置１であって、微細藻類の培養方法では、培養液Ｓから微細藻類を除去して分離液を得る分離工程と、分離液に炭酸物質を溶解させて溶解液Ｗを得る溶解工程と、溶解液Ｗと前記培養液Ｓを接触させ、前記培養液Ｓに炭素源を供給する供給工程とを有する。微細藻類の培養装置１は、培養液Ｓを収容する培養槽１０と、培養液Ｓから微細藻類を除去して分離液を得る分離手段２０と、分離液に炭酸物質を溶解させて溶解液Ｗを得る溶解手段３０と、溶解液Ｗと前記培養液Ｓを接触させ、前記培養液Ｓに炭素源を供給する供給手段４０とを備える。【選択図】図１
