Patent ID: 8908353

Claim:
A laminated ceramic capacitor having: a ceramic laminate of roughly rectangular solid shape constituted by multiple layered dielectric ceramic layers which in turn are constituted by a dielectric ceramic constituted by primary phase grains whose primary component is BaTiO 3 , secondary phase grains containing at least Re (Re represents at least one of Eu, Gd, Dy, Ho, Er, Yb, and Y), Ba, and Ti, and grain boundary phase containing at least one of B (boron) and Li (lithium) or both; internal electrodes which are made of Cu or Cu alloy and formed in a manner opposing each other via the dielectric ceramic and lead out alternately to different end faces; and external electrodes which are formed on both end faces of the dielectric ceramic layers and connected electrically to the internal electrodes led out to the end faces, wherein when a thickness of the dielectric ceramic layer sandwiched between the internal electrodes is given by t, and when grain sizes at cumulative 20%, cumulative 50%, and cumulative 95% points of a cumulative count distribution obtained by measuring sizes of the primary phase grains in the dielectric ceramic layer are given by D20, D50, and D95, respectively, D20≦D50×70%, D50≦t/4, D95≦t/2, and CV value ((standard deviation between D20 and D95)/D50)<40% are satisfied.
