A nonreducing dielectric ceramic has a perovskite structure represented by the formula ABO3 with a principal crystal phase comprising barium titanate as a principal constituent. The crystal axis ratio c/a determined by an X-ray diffraction method at a temperature of -25°C or more satisfies the relationship 1.000 ≤ c/a ≤ 1.003. Preferably, the nonreducing dielectric ceramic has a phase transition point of less than -25°C. Preferably, the nonreducing dielectric ceramic contains at least one rare-earth element. A monolithic ceramic capacitor including dielectric ceramic layers composed of a nonreducing dielectric ceramic in accordance with the present invention is also disclosed.
