Dielectric ceramic composition and ceramic electronic device

KANEKO TOSHIHIKO / FUJINO TATSUYA / YOSHIDA TAKERU / EBINA HARUKI / MORIGASAKI NOBUTO

A dielectric ceramic composition and a ceramic electric device having a dielectric layer composed of the dielectric ceramic composition including a main component having a perovskite crystal structure expressed by general formula ABO3, an oxide of Eu, an oxide of Ra (Sc, Er, Tm, Yb and Lu), an oxide of Rb (Y, Dy, Ho, Tb and Gd) and an oxide of Si, in which 0.075≦α≦0.5, 0.5≦β≦3, 1.0≦γ≦4, 1.5≦δ≦5, and 0.030≦α/δ≦0.250 where a content of an oxide of Eu is α mole, a content of the oxide of Ra is β mole, a content of the oxide of Rb is γ mole, and a content of the second sub-component is δ mole with respect to 100 moles of the main component.
