A recovery apparatus of carbon dioxide comprises: an absorption column which brings a gas containing carbon dioxide into contact with an absorbing liquid and allows the absorbing liquid to absorb carbon dioxide; a regeneration column for regenerating the absorbing liquid, by causing the absorbing liquid having carbon dioxide absorbed in the absorption column to release carbon dioxide; a circulation system which circulates the absorbing liquid so that the absorbing liquid flowing from the absorption column returns to the absorption column through the regeneration column; and a steam supply system which generates steam available for a heat source that regenerates the absorbing liquid, using at least one of the absorbing liquid that returns to the absorption column by the circulation system and the absorbing liquid in the absorption column, and supplies the steam to the regeneration column. Absorption of carbon dioxide and release/regeneration are repeated, high temperature steam is generated from the absorbing liquid that returns to the absorption column and the absorbing liquid in the absorption column, and the steam is provided to the regeneration column to use as a heat source for regenerating the absorbing liquid.
