PROBLEM TO BE SOLVED: To provide a simple manufacturing method of microbubble precursor generating microbubbles of high concentration. SOLUTION: The manufacturing method of a microbubble precursor containing a surfactant and water-soluble solid matter, comprises a process 1 for obtaining supersaturated solution containing the surfactant and water-soluble solid matter, and a process 2 for mixing the supersaturated solution obtained in the process 1 with a lean solvent and mechanically treating them. The surfactant preferably has a 16-24C alkyl group. COPYRIGHT: (C)2009,JPO&INPIT
