Abstract:
A composite laminated ceramic electronic component that includes co-fired low dielectric-constant ceramic layers and high dielectric-constant ceramic layers. The low dielectric-constant ceramic layers and high dielectric-constant ceramic layers are each composed of a glass ceramic containing: a first ceramic composed of MgAl2O4 and/or Mg2SiO4; a second ceramic composed of BaO, RE2O3 (RE is a rare-earth element), and TiO2; glass containing each of 44.0 to 69.0 weight % of RO (R is an alkaline-earth metal), 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 MnO, and the content ratios of the glass, etc. are varied between the low dielectric-constant ceramic layers and the high dielectric-constant ceramic layers.
