Abstract
A multilayer ceramic capacitor includes a substantially cuboid-shaped laminated body formed with alternately stacked conductive layers and ceramic dielectric layers, and a pair of external electrodes respectively disposed at opposite end portions of the laminated body. The conductive layers are corrugated, and each of the conductive layers has a nonuniform and spatially varying thickness. Thus the surface area of the conductive layers is substantially increased, which in turn results in the increment of the electrostatic capacitance of the multilayer ceramic capacitor. Further, interrupted regions having the layer thickness of zero are formed on the conductive layer and since the boundary portions are pointed toward neighboring conductive layers, a strong electric field is formed threat. Accordingly, the electrostatic capacitance becomes increased.
