PROBLEM TO BE SOLVED: To provide a method of producing nano-bubble and a nano-bubble producing device, enabling a liquid containing nano-bubble of wanted quantity to be easily obtained when required.SOLUTION: A method of producing nano-bubble includes a sealing step in which water and air is sealed in a container having flexibility, a pressurizing step in which the container having been subjected to the sealing step is pinched by a pinching device so that the interior of the container is pressurized, a supersaturation dissolving state generation step in which, in a state where the container is pinched by the pinching device, the container is shaken as the entire pinching device, and causes the inside of the container to be supersaturation dissolving state by releasing pinching of the pinching device, and an ultrasonic wave radiation step which radiates ultrasonic wave to the container of which pinching by the pinching device has been released. |
