    摘要: An apparatus of a polycarbonate resin having polymerization tanks is provided. In supplying a molten reactant to a liquid phase in a polymerization tank, or supplying the molten reactant to a gas phase in the polymerization tank by an insertion pipe, in at least one polymerization tank, and/or producing a polycarbonate resin by an ester exchange reaction between an aromatic dihydroxy compound and a carbonic diester by using three vertical polymerization tanks and one horizontal polymerization tank, a wall surface temperature T of a distillation pipe is set higher than a boiling point t1 of by-produced phenol such that the relationship of the boiling point t1 of the by-produced phenol under a pressure in at least a third vertical polymerization tank, the wall surface temperature T of the distillation pipe and an inner temperature t2 of the third vertical polymerization tank satisfies t1
