Abstract
A laminated ceramic capacitor which has high moisture resistance includes a laminated body including a plurality of stacked ceramic layers and internal electrodes placed between the ceramic layers; and an external electrode formed on an outer surface of the laminated body and electrically connected to the internal electrodes, and the laminated ceramic capacitor has the feature that the ceramic layers contain CaZrO3 as their main constituent, and the feature that a layer containing a (Ba, Ca)—Zn—Si based oxide (including an oxide containing no Ca) is formed between the laminated body and the external electrode.
Claims16
A laminated ceramic capacitor comprising:
- a laminated body comprising a plurality of stacked ceramic layers and internal electrodes disposed between ceramic layers;
