摘要：
A microbubble producing device is constructed by coaxially joining a spiral flow producing blade-type nozzle and a vortex breaking nozzle. A spiral flow of liquid, to the center of which flow a gas is introduced, is produced by the spiral flow producing blade-type nozzle. When the spiral flow is supplied to a flow restriction section of the vortex breaking nozzle, microbubbles are produced from a vortex breaking section. The gas is introduced into the liquid by an air supply device.
