Provided is a manufacturing method for a high molecular weight aromatic polycarbonate resin that has superior fluidity and for which a good color and a sufficiently high molecular weight can be achieved. A manufacturing method for a high molecular weight aromatic polycarbonate resin includes: a step in which a dialcohol compound expressed by general formula (1) and a catalyst are mixed to obtain a catalyst composition; a step in which the obtained catalyst composition is kept in a molten state, and is mixed with an aromatic polycarbonate prepolymer within ten hours after obtaining the catalyst composition, to obtain a prepolymer mixture; and a high molecular weight achievement step in which the obtained prepolymer mixture is heat-treated under reduced pressure conditions to obtain a high molecular weight aromatic polycarbonate resin.
