To provide a production method of a polycarbonate, where a polycarbonate excellent in the light resistance, transparency, color hue, heat resistance, thermal stability, mechanical strength and the like can be efficiently and stably produced. A method for producing a polycarbonate, comprising: continuously feeding a dihydroxy compound having a portion represented by -(-CH 2 -O-)- in a part of a structure thereof and a carbonic acid diester; and continuously performing polycondensation to produce a polycarbonate, wherein the method satisfies all of the conditions: (A) at least two reactor vessels connected in series are used; (B) a reaction solution reacted in a first reactor of the first vessel is continuously fed to a reactor of the second vessel; (C) the first reactor is equipped with a reflux condenser; and (D) a reflux ratio in the first reactor is from 0.01 to 10 based on a distillate volume. |
