Abstract: The present invention provides a micro two-phase droplet generating device that does not require separate through-holes corresponding to a plurality of two-phase dispersed parallel continuous flow channels. The micro two-phase droplet generating device of the present application comprises a row of a plurality of microflow channels, liquid transfer ports, and a slit, and is configured so as to form two-dispersion phase parallel continuous flows at first connection sites between the plurality of microflow channels, in which a first dispersion phase flows, and the slit, through which a second dispersion phase flows. A continuous phase is fed to second connection sites between the plurality of microflow channels, in which the two-dispersion phase parallel continuous flows flow, and another liquid transfer port, which is preferably a second slit, downstream of the slit, and the two-dispersion phase parallel continuous flows are sheared at the second connection sites, whereby two-phase droplets, and in particular, core-shell or Janus two-phase droplets, can be generated, and a product can be collected from a discharge port.
