A method for producing an anion-exchanging LDH using a carbonate ion-type layered double hydroxide represented by general formula QaT(OH)z(CO32−)0.5-b/2(X−)b.nH2O (where 1.8≦a≦4.2, z=2(a+1), 0≦b0.5, 0≦n≦5, Q represents divalent metal, T represents trivalent metal, and X− is an element or atom group that turns to monovalent anion) as a starting material, with value b increased at least to 0.5 and a maximum of 1, wherein the carbonate ion-type layered hydroxide is made to contact an alcoholic solution containing an acidic compound (MXm) (where m=1, 2, or 3; when m=1, M is H or NRR′R″.H, with R, R′, and R″ being H or organic group; and when m=2 or 3, M is a metal salt, namely a divalent or trivalent metal).
