PROBLEM TO BE SOLVED: To provide an apparatus for separating a multicomponent mixed liquid by distillation, realizing a liquid level regulation mechanism without using an electronic measuring instrument for measuring the storage quantity of each storage tank at all. SOLUTION: This apparatus for separating the multicomponent mixed liquid by distillation is equipped with a distillation column body (1) having a filling part or plate column part (1a), a reboiler (2) connected to the return end part of the distillation column body (1) and a condenser (3) connected to the terminal part of the distillation column body (1) at one end part thereof, and a reflux tank (4) is arranged between the other end part of the condenser (3) and the filling part or plate column part (1a) of the distillation column body (1) and has a liquid flow-down pipe (5) which consists of an outer pipe (5a) with a female screw fixed to the rear of the bottom part of the reflux tank (4) and an inner pipe (5b) with a male screw fitted to the female screw, and is constituted so that graduations capable of judging the height of the inner pipe from the bottom part of the reflux tank (4) are stamped on the inner pipe (5b) and the height of the inner pipe (5b) from the bottom part of the reflux tank (4) is regulable by the rotation of the inner pipe (5b).
