To provide a gas-liquid mixing apparatus which forms a gas-liquid mixed flow in such a way that fine bubbles are included to the utmost limit.
The gas-liquid mixing apparatus comprises a drum-like body cylinder 1 having a cylindrical inner surface 1a, a liquid feed port 3 which opens to a peripheral surface part of the body cylinder close to its one end face and is used for feeding a liquid into the body cylinder in one direction substantially in the circumferential tangential direction of the peripheral surface part, a gas supply port 2 for supply the gas into the body cylinder disposed in a part of the body tube close to the liquid feed port, the arrangement of baffle plates 4 protruded at a tilt from the cylindrical inner surface in such a way that the plates flutter in one direction in the tangential direction, and an outlet chamber formed by drawing a cylindrical inner part at the other end of the body cylinder into a cone shape 1b and truncating the resulting conical part at an outlet hole 5 whose vertex part is arranged in the other end face of the body cylinder.
