The objective of the present invention is to provide a device for adsorbing and emitting carbon dioxide, the device having high adsorption abilities and low energy consumption at the time of adsorption and desorption. The device for adsorbing and emitting carbon dioxide comprises a pair of electrodes (electrode (1) and electrode (2)) provided facing each other, an electrolyte (3) filled between the electrode (1) and electrode (2) of the pair of electrodes, and a porous body (4) provided on the electrode (1) of the pair of electrodes, and is characterized in that the electrolyte (3) is capable of forming carbonate ion or hydrogen carbonate ion by absorbing carbon dioxide and dissolving the carbon dioxide therein, and in that the porous body (4); electrostatically adsorbs the carbonate ion or hydrogen carbonate ion on the surface thereof when voltage is applied to the pair of electrodes in a forward direction, and electrostatically emits the carbonate ion or hydrogen carbonate ion from the surface thereof when
