Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a distillation method and a distillation device therefor which is miniaturized and whose occupancy area is made small and whose cost is lowered. SOLUTION: A distillation device is provided with a first column 71 extending upward from the bottom, a second column 72 arranged adjacently to the first column 71 through a mid partition 23, and a third column 73 extending downward from the top and communicating with the first column 71 and the second column 72. Raw liquid containing plural components is fed into the first column 71, and vapor discharged from its top is condensed to turn it into liquid, and the liquid is discharged to the outside as a distillate. A part of the distillate is returned as a reflux to the third column 73, and the reflux is distributed among the first column 71 and the second column 72, and liquid is discharged as a bottom product from each of the bottoms of the first column 71 and the second column 72.
