Abstract
A composite laminate 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 at least one of MgAlOand MgSiO; a second ceramic composed of BaO, REO(RE is a rare earth element), and TiO; glass containing each of 44.0-69.0 wt % of RO (R is an alkaline-earth metal), 14.2-30.0 wt % of SiO, 10.0-20.0 wt % of BO, 0.5-4.0 wt % of AlO, 0.3-7.5 wt % of LiO, and 0.1-5.5 wt % of MgO; and MnO. The content ratios of the first ceramic, second ceramic, glass, and MnO are varied between the low dielectric constant ceramic layers and the high dielectric constant ceramic layers, wherein the content of MnO in the low dielectric constant ceramic layers is 7.5-18.5 wt % MnO.
