A multi-parallel processing emulsification machine excellent in ease of priming and cleaning the interior of flow paths, capable of also coping with a liquid that precipitates is provided. A component through which a continuous phase to be the solvent of emulsion flows is stacked over a component through which a disperse phase to be the solute of the emulsion flows. Further, a component through which the produced emulsion flows is stacked thereover to form a microfluidic device for emulsification. When they are stacked together, multiple minute cross-shaped globule production portions are formed and in these globule production portions, the disperse phase flows from downward to upward. The continuous phase merges into them from left and right to form a sheath flow in which the continuous phase encircles the circumference of the disperse phase. In the sheath flow, the disperse phase is divided and turned into globules by a difference in velocity of flow between the continuous phase and the disperse phase. Thus an emulsion is produced and flows upward through the globule production flow paths. All the minute flow paths are so structured that they are open upward. As a result, fine particles in liquid are less prone to precipitate and air can be easily exhausted.
