A continuous solid-state polymerization device according to the present invention comprises: a feeder for injecting a prepolymer continuously; a transverse reactor connected to the feeder via a first connector to receive the prepolymer from the feeder and to perform solid-state polymerization, the reactor itself rotating; and a chamber connected to the transverse reactor via a second connector to receive a polymer, which has been discharged from the transverse reactor, and solid-state polymerization of which has been completed, and to discharge the polymer, wherein the transverse reactor has a demolding coating film formed on the inner wall thereof, and the feeder, the transverse reactor and the chamber are in a vacuum state. The continuous solid-state polymerization device can prevent formation of an interval, in which the prepolymer stagnates, and can perform solid-state polymerization continuously in a vacuum state without using inert gas.
