Abstract
A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner. A dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel such that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.
