The present invention provides a layered double hydroxide with improved conductivity, a layered double hydroxide and a composite material containing the layered double hydroxide. The layered double hydroxide is represented by the general formula: [Mg 2+ (1-y) M1 ±+ y ] 1-x [Al 3+ (1-z) M2 ²+ z ] x (OH) 2 A n- x/n ·mH 2 O, wherein 0.1‰¦x‰¦0.4, 0‰¦y‰¦0.95, and 0‰¦z‰¦ 0.95, with the proviso that both y and z are not 0 at the same time; ±=1 or 2; ²=2 or 3; A n- is an n-valent anion, with the proviso that n is an integer of 1 or greater; m‰§0; M1 ±+ is a cation of at least one substituent element selected from the group consisting of monovalent elements, transition metal elements, and other elements with an ionic radius greater than that of Mg 2+ ; and M2 ²+ is a cation of at least one element selected from the group consisting of divalent elements, transition metals, and other elements with an ionic radius greater than that of Al3 + .
