A method for producing bisphenol A, comprising the following step A to step F, step H, and step I: step A: a step of degrading a polycarbonate resin in a solvent to obtain a reaction liquid a1 containing bisphenol A, and distilling off the solvent from the obtained reaction liquid a1 to obtain a crude solution A having a bisphenol A content of less than 90% by mass; step B: a step of subjecting acetone and phenol to dehydration condensation in the presence of an acid catalyst to obtain a reaction liquid B containing bisphenol A; step C: a step of distilling off unreacted acetone and water from the reaction liquid B obtained in the step B to obtain a concentrated liquid C; step D: a step of subjecting the concentrated liquid C obtained in the step C to crystallization to obtain a slurry liquid, and subjecting the slurry liquid to solid-liquid separation to obtain a mother liquor D and a cake d; step E: a step of purifying the cake d obtained in the step D to obtain bisphenol A; step F: a step of circulating part of the mother liquor D obtained in the step D to supply to the step B; step H: a step of obtaining a solution H1 or a solution H2 from the crude solution A and part of the mother liquor D, wherein the solution H1 is a solution containing bisphenol A obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and isopropenylphenol under conditions that allow degradation of bisphenol A and then rebonding phenol and isopropenylphenol, and the solution H2 is a solution containing phenol obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and acetone under conditions that allow degradation of bisphenol A; and step I: a step of supplying the solution H1 or the solution H2 obtained in the step H to the step B and/or the step C. step A: a step of degrading a polycarbonate resin in a solvent to obtain a reaction liquid a1 containing bisphenol A, and distilling off the solvent from the obtained reaction liquid a1 to obtain a crude solution A having a bisphenol A content of less than 90% by mass; step B: a step of subjecting acetone and phenol to dehydration condensation in the presence of an acid catalyst to obtain a reaction liquid B containing bisphenol A; step C: a step of distilling off unreacted acetone and water from the reaction liquid B obtained in the step B to obtain a concentrated liquid C; step D: a step of subjecting the concentrated liquid C obtained in the step C to crystallization to obtain a slurry liquid, and subjecting the slurry liquid to solid-liquid separation to obtain a mother liquor D and a cake d; step E: a step of purifying the cake d obtained in the step D to obtain bisphenol A; step F: a step of circulating part of the mother liquor D obtained in the step D to supply to the step B; step H: a step of obtaining a solution H1 or a solution H2 from the crude solution A and part of the mother liquor D, wherein the solution H1 is a solution containing bisphenol A obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and isopropenylphenol under conditions that allow degradation of bisphenol A and then rebonding phenol and isopropenylphenol, and the solution H2 is a solution containing phenol obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and acetone under conditions that allow degradation of bisphenol A; and the solution H1 is a solution containing bisphenol A obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and isopropenylphenol under conditions that allow degradation of bisphenol A and then rebonding phenol and isopropenylphenol, and the solution H2 is a solution containing phenol obtained by degrading bisphenol A contained in the crude solution A and the mother liquor D into phenol and acetone under conditions that allow degradation of bisphenol A; and step I: a step of supplying the solution H1 or the solution H2 obtained in the step H to the step B and/or the step C.
