The layered double hydroxide is characterized by comprising base layers each comprising a metal double hydroxide represented by the formula: M(II)1-XM(III)X(OH)2 (wherein M(II) represents one or two bivalent metal atoms; M(III) represents a trivalent metal atom; and x represents 0.2 to 0.33), and an intermediate layer and interlayer water each intercalated between the base layers, wherein the intermediate layer comprises a compound represented by the formula: R1-COOH or R2-SO3H (wherein R1 and R2 independently represent at least one substituent selected from an aliphatic hydrocarbon group, a substituted aliphatic hydrocarbon group, an aromatic hydrocarbon group, a substituted aromatic hydrocarbon group, a heterocyclic group and a substituted heterocyclic group). |
