Provided is a thermally stable bisphenol composition whose increase in the Hazen color number is suppressed even under higher temperature conditions. A bisphenol composition including an aryl alkyl sulfide or a dialkyl disulfide at 0.1 ppb by mass to 1% by mass with respect to a bisphenol. A bisphenol composition including an aryl alkyl sulfide or a dialkyl disulfide at a predetermined ratio is thermally stable in terms of the Hazen color number, and shows no coloring problem under high temperature conditions. By using such a bisphenol composition, a polycarbonate resin having an excellent color tone can be produced.
