PROBLEM TO BE SOLVED: To perform optimum culture, even if the concentration of the culture solution becomes high, by effectively irradiating photosynthetic organisms, such as algae, with the light of a high-efficiency lamp. SOLUTION: The photobioreactor is provided with a culture vessel 4 for holding a culture solution, a rotary shaft 12 rotatably placed in the culture vessel 4 and a field-emission lamp 16 fixed to the rotary shaft 12. The rotary shaft 12 is rotated, in a controlled manner of making the lamp 16 rotate about the rotary shaft, while making the lamp act as a stirring member for the culture solution, the light intensity and lighting of the lamp 16 are controlled to irradiate the culture solution with light of desired intensity, and the on/off timing of the lamp 16 is controlled to control the light reaction and the dark reaction of the photosynthetic organism, such as algae.
