A bisphenol composition includes 95% or more by mass of a bisphenol and 200 mass ppm or more of a compound represented by the following general formula (II):
In formula (II), R
21
and R
22
denote a methyl group or a hydrogen atom; R
22
is a methyl group when R
21
is a hydrogen atom; R
22
is a hydrogen atom when R
21
is a methyl group; R
23
to R
25
independently denote a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; and R
23
, R
24
, and R
25
may be bonded or cross-linked between two of the groups. A method for producing a polycarbonate resin using the bisphenol composition is also described.
