PURPOSE: A fixing method of carbon dioxide is provided to improve fixing efficiency and to reduce volume of generated material by condensation polymerization of carbon dioxide. CONSTITUTION: A fixing method of carbon dioxide is provided to inject carbon dioxide into a reactor with strong aqueous solution, thereby polymerizing carbonic acid through a condensation polymerization. The temperature of the reactor is maintained at 100°C or less. The pressure of the carbon dioxide is 30 atmospheric pressure or more. The pH of the strong acid aqueous solution is 2 or less and includes sulfuric acid, nitric acid, or hydrochloric acid.
