Patent ID: 7446997

Claim:
A multi-layer ceramic capacitor, comprising: a plurality of dielectric ceramic layers; internal electrodes formed opposed between the dielectric ceramic layers and extracted alternately to different end surfaces; and end termination electrodes formed on both end surfaces of the dielectric ceramic layers and electrically connected to each of the internal electrodes, wherein the dielectric ceramic layer is a sintered body constituted of a primary component that, when the primary component is expressed by ABO 3 +aRe 2 O 3 +bMnO (wherein ABO 3 expresses perovskite dielectrics mainly made of BaTiO 3 , Re 2 O 3 is an oxide of at least one kind selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y and a and b express numbers of moles relative to 100 mole of ABO 3 ), satisfies 1.000≦A/B≦1.035, 0.05≦a≦0.75 and 0.25≦b≦2.0; and a subcomponent that includes at least one kind of B, Li or Si in the range of 0.16 to 1.6 parts by mass in total in terms of B 2 O 3 , Li 2 O and SiO 2 ; and the internal electrode is constituted of Cu or a Cu alloy.
