    • The present invention relates to a production apparatus of a polycarbonate resin in which generation of adherents or foreign matters in a polymerization tank is reduced, and a production method of a polycarbonate resin in which crystallized foreign matters or burned foreign matters are reduced, by melt method. The present invention relates to a continuous production apparatus of a polycarbonate resin using a plurality of polymerization tanks, wherein when 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, equipped with a stirring device, a wall surface temperature T of a distillation pipe 10c is set to a temperature higher than a boiling point t1 of by-produced phenol such that the relationship of the boiling t1 of the by-produced phenol under a pressure in at least a third vertical polymerization tank 14, the wall surface temperature T of the distillation pipe 10c and an inner temperature t2 of the third vertical polymerization tank 14 is satisfied with the formula (1). t1
