The present invention relates to a photobioreactor for microalgae cultivation having a bubble circulation structure, which allows gas flowing into a cultivation space to generate a vortex and thus circulate microalgae, thereby improving cultivation efficiency of the microalgae. A photobioreactor for microalgae cultivation according to an embodiment of the present invention includes a cultivation panel major body having the cultivation space into which the microalgae are injected to be cultivated; a gas supply pipe provided at a lower portion of the cultivation panel major body to pass through the cultivation space in a transverse direction and thus discharge inflow gas; and at least one vortex forming partition extending in a transverse direction from an internal wall of the cultivation panel major body and formed to have an arc shape and thus cause a vortex to an ascending current of gas supplied through the gas supply pipe.
