The structure and dielectric properties of charge-ordered Nd 1.75 Sr 0.25 NiO 4 ceramics are presented. The giant dielectric constant about 30 000 is observed in the present ceramics even the frequency is up to 5 MHz. There are three dielectric relaxations at the curve of temperature dependence of d
