Composite Laminated Ceramic Electronic Component

A composite laminated ceramic electronic component comprising:

• a first dielectric-constant ceramic layer and a second dielectric-constant ceramic layer that are stacked, the first dielectric-constant ceramic layer having a lower dielectric constant than the second dielectric-constant ceramic layer, wherein
• the first dielectric-constant ceramic layer and the second dielectric-constant ceramic layer each comprises:
• a glass ceramic containing:
• (1) a first ceramic comprising at least one of MgAl2O4 and Mg2SiO4;
• (2) a second ceramic including BaO, RE2O2, and TiO2;
• (3) glass containing each of 44.0 to 69.0 weight % of RO, 14.2 to 30.0 weight % of SiO2, 10.0 to 20.0 weight % of B2O3, 0.5 to 4.0 weight % of Al2O3, 0.3 to 7.5 weight % of Li2O, and 0.1 to 5.5 weight % of MgO;
• and
• (4) MnO,
• wherein RE is a rare-earth element,
• wherein R is at least one alkali-earth metal selected from Ba, Ca, and Sr,
• wherein the first dielectric-constant ceramic layer:
• contains 47.55 to 69.32 weight % of the first ceramic;
• contains 6 to 20 weight % of the glass;
• contains 7.5 to 18.5 weight % of the MnO;
• contains, as the second ceramic, each of 0.38 to 1.43 weight % of BaO, 1.33 to 9.5 weight % of RE2O3, and 0.95 to 6.75 weight % of TiO2;
• and
• has a relative permittivity of 15 or less, and wherein the second dielectric-constant ceramic layer:
• contains 15.5 to 47 weight % of the first ceramic;
• contains 7 to 20 weight % of the glass;
• contains 5.5 to 20.5 weight % of the MnO;
• contains, as the second ceramic, each of 2.1 to 5.2 weight % of BaO, 13.2 to 34.75 weight % of RE2O3;
• and 9.5 to 24.75 weight % of TiO2;
• and
• has a relative permittivity of 20 or more and 25 or less.
