复合层叠陶瓷电子部件
摘要：
本发明提供一种具备被共烧成的低介电常数陶瓷层和高介电常数陶瓷层、且在低介电常数陶瓷层以及高介电常数陶瓷层的各个层中可得到相应的特性的复合层叠陶瓷电子部件。由玻璃陶瓷构成低介电常数陶瓷层(3)和高介电常数陶瓷层(4)，在低介电常数陶瓷层(3)和高介电常数陶瓷层(4)中使玻璃等的含有比率不同，其中该玻璃陶瓷包含：由MgAl2O4以及／或者Mg2SiO4构成的第一陶瓷；由BaO、RE2O3(RE为稀土类元素)以及TiO2构成的第二陶瓷；分别包含44.0～69.0重量％的RO(R为碱土类金属)、14.2～30.0重量％的SiO2、10.0～20.0重量％的B2O3、0.5～4.0重量％的Al2O3、0.3～7.5重量％的Li2O、以及0.1～5.5重量％的MgO的玻璃；和MnO。
摘要（英）：

Provided is a composite laminate ceramic electronic component comprising a low-permittivity ceramic layer and a high-permittivity ceramic layer, both of which are fired, in which suitable characteristics are achieved in both the low-permittivity ceramic layer and the high-permittivity ceramic layer. Low-permittivity ceramic layers (3) and high-permittivity ceramic layers (4) are configured from a glass ceramic containing: a first ceramic composed of MgAl2O4 and/or Mg2SiO4; a second ceramic composed of BaO, RE2O3 (RE being a rare-earth element), and TiO2; a glass containing 44.0-69.0 wt% of RO (R being an alkaline earth metal), 14.2-30.0 wt% of SiO2, 10.0-20.0 wt% of B2O3, 0.5-4.0 wt% of Al2O3, 0.3-7.5 wt% of Li2O, and 0.1-5.5 wt% of MgO; and MnO; and the content ratio of the glass or the like differs between the low-permittivity ceramic layers (3) and the high-permittivity ceramic layers (4).
