MULTILAYER CERAMIC CAPACITOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18661768 titled 'MULTILAYER CERAMIC CAPACITOR
The multilayer ceramic capacitor described in the patent application consists of dielectric layers made of ceramic material and inner electrode layers that are laminated together. Each inner electrode layer contains a first metal as the main component, along with dielectric coupling portions that penetrate through in a lamination direction, filled with a portion of adjacent dielectric layers, and couple the adjacent dielectric layers to each other. A solid-dissolved layer, where a second metal different from the first metal is solid-dissolved, is provided at the interface between the dielectric coupling portions and the inner electrode layers. The content of the second metal in the solid-dissolved layer ranges from about 0.1 mol % to about 10 mol % in 100 mol of the first metal.
- Dielectric layers made of ceramic material

Original Abstract Submitted
A multilayer ceramic capacitor includes dielectric layers made of a ceramic material and inner electrode layers that are laminated. Each of the inner electrode layers includes a first metal as a main component, and dielectric coupling portions penetrating through in a lamination direction, filled with a portion of adjacent dielectric layers, and coupling the adjacent dielectric layers to each other. A solid-dissolved layer, in which a second metal different from the first metal is solid-dissolved, is provided at an interface between the dielectric coupling portions and the inner electrode layers. A content of the second metal in the solid-dissolved layer is about 0.1 mol % or more and about 10 mol % or less in 100 mol of the first metal.
