The purpose of the present invention is to reduce the amount of a reclamation gas supplied into a carbon-dioxide recovery tower in a step in which a carbon-dioxide capturing material is reclaimed, improve energy efficiency, and reduce the time spent on the reclamation step. This carbon-dioxide recovery apparatus is provided with: a carbon-dioxide absorption tower in which a carbon-dioxide capturing material is accommodated; a heating unit for heating the carbon-dioxide capturing material; a passage for introducing a carbon-dioxide-containing gas into the carbon-dioxide absorption tower; a passage for introducing a reclamation gas into the carbon-dioxide absorption tower; and a passage for recovering a mixed gas including a gas desorbed from the carbon-dioxide capturing material. The carbon-dioxide capturing material is preheated by the heating unit, and the reclamation gas is subsequently introduced into the carbon-dioxide absorption tower, and carbon dioxide is recovered from the carbon-dioxide capturing material.
