1. A microfluidic mixer comprising:
a first microchannel with a first inlet and a second inlet, through which a fluid is introduced, being formed on one end of the first microchannel and a first outlet, through which the fluid is discharged, being formed on another end of the first microchannel; and
at least two disk-shaped mixing units disposed between the first inlet and second inlet and the first outlet, the at least two disk-shaped mixing units including a U-shaped first protruding portion and a U-shaped second protruding portion,
wherein the U-shaped first protruding portion is disposed inside the U-shaped second protruding portion,
wherein each of the at least two disk-shaped mixing united has a two-layer structure with a lower portion and an upper portion, and
wherein the lower portion of each of the at least two disk-shaped mixing units is formed as a disk-shaped space and the U-shaped first and second protruding portions are formed in the upper portion.
