A monolithic ceramic capacitor includes dielectric ceramic layers having a thickness of less than 1 μm. When this thickness is t and the crystal grains of a dielectric ceramic of the layers have a mean diameter of r, a mean number N of grain boundaries satisfies 0<N≦̸2 where N=t/r−1. The dielectric ceramic contains, as a main component, a perovskite type compound ABO3 (where A is Ba or Ba and at least one of Ca and Sr, B is Ti or Ti and at least one of Zr and Hf), and further contains Mn and V as auxiliary components. On the basis of 100 molar parts of the main component, the content of Mn is 0.05 to 0.75 molar parts, the content of V is 0.05 to 0.75 molar parts, and the total content of Mn and V is 0.10 to 0.80 molar parts. |
