Carbon dioxide absorbent containing a hetero metallic oxide porous material formed by uniformly mixing carbon dioxide absorbing metallic oxides with support metallic oxides is provided. Also, a manufacturing method of carbon dioxide absorbent, which comprises a step of forming a mixed solution which a precursor of carbon dioxide absorbing metallic oxides and a precursor of support metallic oxides are mixed; and a step of obtaining a precipitate by making the mixed solution react by a liquid-phase method; and a step of obtaining a hetero metallic oxide porous material by firing the precipitate, is provided.
