| 1. A carbon dioxide adsorption element for adsorbing carbon dioxide contained in air, comprising:
a foil-like or plate-like support member,
a porous aluminum oxide film covering said support member,
amine groups clinging to the inner surface of each pore of said film for carbon dioxide adsorption,
said film being formed by oxidation of aluminum or aluminum alloy,
wherein
the depth direction of each pore of said film is the thickness direction of said support member.
