PROBLEM TO BE SOLVED: To provide a gas-liquid mixing apparatus efficiently imparting ultrasonic vibration to a liquid mixed with a gas and uniformly dispersing or dissolving the gas in the liquid. SOLUTION: The gas-liquid mixing apparatus includes an outer container 20 configured of a large diameter part 21, a small diameter part 22, and a shifting part 23; an inner container 30 arranged in the outer container, an outer flow path 60 comprised of a first liquid space 61 arranged at a position corresponding to the large diameter part, a shifting space 62 arranged at a position corresponding to the shifting part, and a second liquid space 63 corresponding to the small diameter part; a mixing space 70 having an opening opened to the second liquid space; a gas jetting nozzle 52 for jetting the gas toward the mixing space; a liquid flow-in pipe 51 extending from the outside of the outer container to the first liquid space and releasing the liquid along the side wall of the large diameter part; a dissolving solution discharge pipe 53 extending from the mixing space to the outside of the outer container; and an ultrasonic wave transmitting means 40 for transmitting the ultrasonic vibration toward the mixing space.
