PROBLEM TO BE SOLVED: To provide a carbon dioxide reduction apparatus capable of holding a carbon dioxide on an electrode and efficiently supplying the carbon dioxide to a reaction field and recovering a produced material from the reaction field.SOLUTION: A carbon oxide reduction apparatus includes an anode electrode, a liquid holding film capable of holding an electrolyte, a proton transmission film and a cathode electrode. The cathode electrode includes a metal capable of reducing a carbon dioxide, and further includes a metal-containing member having a hole that allows a passage of a carbon dioxide in a thickness direction and an adsorbent on a surface of the metal-containing member on a proton transmission film side, the adsorbent capable of absorbing a carbon dioxide.SELECTED DRAWING: Figure 4A 【課題】 電極上に二酸化炭素を保持でき、かつ反応場への二酸化炭素の供給と、反応場からの生成物の回収とを効率的に行うことができる二酸化炭素還元装置の提供。【解決手段】 アノード電極と、電解液を保持可能な保液膜と、プロトン透過膜と、カソード電極とを有し、前記カソード電極が、二酸化炭素を還元可能な金属を有し、かつ厚み方向に二酸化炭素を通過可能な孔を有する金属含有部材と、前記プロトン透過膜側の前記金属含有部材の表面に、二酸化炭素を吸着可能な吸着剤と、を有する酸化炭素還元装置である。【選択図】図４Ａ
