Claim:
A monolithic ceramic capacitor comprising: a capacitor body comprising a stack of a plurality of dielectric ceramic layers comprising a dielectric ceramic containing crystal grains and crystal grain boundaries, and a plurality of inner electrodes, each of which is disposed at a different interface between adjacent dielectric ceramic layers; and a plurality of outer electrodes disposed at different locations on outer surfaces of the capacitor body and electrically connected to the inner electrodes, wherein, when the dielectric ceramic layers sandwiched between the inner electrodes adjacent to each other in a stacking direction of the stack have a thickness of t μm, and the crystal grains of the dielectric ceramic have a mean diameter of r μm, the thickness t is less than 1 μm and a mean number N of the grain boundaries satisfies 0<N≦2 where N=t/r−1, and the dielectric ceramic contains, as a main component, a perovskite type compound represented by ABO 3 where A is Ba or Ba and at least one of Ca and Sr, and B is Ti or Ti and at least one of Zr and Hf; and the dielectric ceramic further contains Mn and V as auxiliary components where, on the basis of 100 molar parts of the main component, the content of Mn is 0.05 molar parts to 0.75 molar parts, the content of V is 0.05 molar parts to 0.75 molar parts, and the total content of Mn and V is 0.10 molar parts to 0.80 molar parts.
