ABSTRACT:
A multilayer ceramic capacitor1having internal electrode layers3and internal dielectric layers2having thickness of at most 3.5 μm wherein; the internal dielectric layers2comprising dielectric particles contacting the internal electrode layers (contacting dielectric particles2a) and dielectric particles not contacting the internal electrode layers (non-contacting dielectric particles2b), and when an average particle size of an entire plural number of dielectric particles included in the internal dielectric layers2is D50, and standard deviation for particle size range of the contacting dielectric particles is σ, the multilayer ceramic capacitor satisfy the following equations; D50≦0.25 μm and σ≦0.14. According to the present invention, multilayer ceramic capacitor1is provided wherein the capacitor is expected to have improved DC bias characteristic even when the internal dielectric layers2are made thinner.
