PROBLEM TO BE SOLVED: To provide a photosynthesis culture device which can correspond to the changes of weather and also to the annual and daily changes of sun altitude and enables the efficient culture of photosynthesis organisms, and to provide a method for the photosynthesis culture. SOLUTION: This photosynthesis culture device is characterized by containing the following requirements (1) and (2). (1) A culture tank 1 in which a culture liquid 2 containing photosynthesis organisms and one or more light-dispersing members 3 for dispersing and irradiating incident solar light as a light source in the culture liquid 2 are received; and (2) a liquid surface level control device 12 which is disposed at a place near to the culture tank 1, can process data comprising a cell concentration in the culture liquid 2, one or more kinds of information selected from meteorological observation weather forecast information and solar light intensity, and the liquid surface level of the culture liquid as input information, and can calculate a relation suitable for culturing the photosynthesis organisms between the light incidence sites of the light-dispersing members 3 and the liquid surface level of the culture liquid, and can control the liquid surface level.
