发明名称 積層セラミックコンデンサおよびその製造方法
摘要 A multilayer ceramic capacitor having a multilayer ceramic element with internal electrodes opposed to each other and dielectric ceramic layers interposed therebetween, and external electrodes on a surface of the multilayer ceramic element and electrically connected to the internal electrodes. The external electrodes contain a first non-precious metal as a first conductive component, and glass containing BaO and/or SrO, where a total content of the BaO and/or the SrO is 34 mol % or more. The internal electrodes have a second non-precious metal different from the first non-precious metal included in the external electrodes. A glass layer is formed at interfacial parts between the ceramic layers and the external electrodes, and a diffusion length thereof is within a range of 1 μm to 5 μm from joint interfaces between the external electrodes and the internal electrodes at the joints.
