Abstract: The invention provides a mixer capable of mixing two kinds of liquids with each other while varying a mixing ratio in a wide range of the flow rates thereof by causing the two liquids in trace amounts to come into contact with each other, or a mixer capable of mixing in short time. The mixer comprises a mixing chamber very low in profile for effecting mixing reaction, and micro-nozzles, provided at a high density in the upper face and lower face thereof, respectively. The mixer is a mixer wherein micro-nozzles are provided in the inner walls of a mixing chamber, respectively, so as to oppose each other, and two liquids are spurted from the micro-nozzles, respectively, thereby implementing mixing by taking advantage of a diffusion phenomenon. Since the two liquids in trace amounts are ejected from the micro-nozzles, respectively, in such a way as to oppose each other, the two liquids in trace amounts come into contact with each other, thereby enabling diffusion mixing in short time.
