In addition, a method for producing a recycled polycarbonate resin or the like by using a useful substance such as the bisphenol or the like is provided. A method for producing a bisphenol, including degrading a polycarbonate resin in the presence of an aromatic monoalcohol, water, and a catalyst. A method for producing carbon dioxide, including recovering carbon dioxide generated by the method for producing a bisphenol. A method for producing a carbonic acid diester by using the carbon dioxide. A method for producing a recycled polycarbonate resin by using the bisphenol and/or the carbonic acid diester. A method for producing an epoxy resin and a method for producing an epoxy resin cured product, by using the bisphenol
