ABSTRACT:
The invention relates to a micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing and reaction (chemical reaction) of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port. A micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing/reaction of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port, the micro fluid chip comprising liquid supplies that supply a plurality of flows, which are formed by division of two kinds of liquids, respectively, in an alternate arrangement, and a flow flattening portion provided downstream of the liquid supplies to be configured in flow passage such that liquids alternately arranged are decreased in dimension as they go downstream and increased in dimension in a direction, which intersects the direction of arrangement and a direction of flow, as they go downstream, to be made substantially the same or slightly large in cross sectional area in the direction of flow. According to the invention, liquids of large flow rates can be processed at high speed and an apparatus is not made large in size.
