摘要

A method for manufacturing an aluminum salt solution includes manufacturing an aluminum salt solution by using, as a raw material, an aluminum hydroxide having T-C (total carbon amount) of 0.04 mass % or less and T-Na2O (total Na2O amount) of less than 0.3 mass %, which is obtained by a Bayer process.
