Claim:
A micro-mixer, comprising: a plurality of passage modules stacked so as to form a multi-tiered flow passage, wherein each passage module of a plurality of said passage modules includes a plurality of combining-dividing units arranged at regular intervals; wherein each of said combining-dividing units includes n number of inlets formed in an upstream surface of the passage module, n number of outlets formed in a downstream surface of the passage module, and a channel connecting said n number of inlets and said n number of outlets, wherein n is at least 2; wherein each of said n number of outlets of each of said combining-dividing units in each of said stacked passage modules is connected with an inlet of a respective different combining-dividing unit in an immediately downstream passage module; and wherein, in each of the combining-dividing units, a flow of a fluid introduced through each of the n number of inlets is divided into n number of partial flows, and a partial flow from each of the n number of inlets is guided to each of the n number of outlets, such that each of the n number of outlets outputs a combined flow including n number of the partial flows taken respectively from the n number of inlets.
