[Name of the Document] The present invention provides an apparatus for producing micro liquid drops through fine channels which can produce a large amount of micro liquid drops at low costs in an efficient manner. The apparatus for producing micro liquid drops according to the present invention includes a fine channel substrate and a holder for holding the fine channel substrate. The fine channel substrate has a micro liquid drop discharge outlet formed at the center thereof; a plurality of micro liquid drop producing sections which are connected to the micro liquid drop discharge outlet via the fine channels and disposed on the respective circumference of M circles or polygons arranged around the micro liquid drop discharge outlet; first-liquid drawing inlets which are disposed on the circumference of a circle or polygon arranged around the micro liquid drop discharge outlet; up-to-Nth-liquid drawing inlets (N is an integer equal to two or greater, M@N-1) which are disposed on the respective circumference of circles or polygons arranged sequentially outward; and the fine channels through which the first- to Nth-liquids are supplied to the plurality of micro liquid drop producing sections. The holder for holding the fine channel substrate has a multi-pipe structure which includes N annular channels for distributing an equal flow of the first- to Nth-liquids to the drawing inlet for each liquid in the fine channel substrate.
