Abstract
A ceramic electronic component includes a first dielectric layer, a second dielectric layer, and an intermediate layer. The first dielectric layer is a layer containing BaO, Nd2O3, and TiO2, the second dielectric layer is a layer containing a different material from the material of the first dielectric layer, and the intermediate layer is a layer formed between the first dielectric layer and the second dielectric layer and containing main components that are not contained in the first dielectric layer and the second dielectric layer in common as the main components.
Claims3
A ceramic electronic component, comprising:
- a first dielectric layer containing BaO, Nd2O3, and TiO2 as main components;
- a second dielectric layer containing Mg2Sia4 as a main component;
- and
- an intermediate layer provided between the first dielectric layer and the second dielectric layer, wherein
- the intermediate layer contains:
- a component that is not contained in the second dielectric layer and is contained only in the first dielectric layer in a boundary between the intermediate layer and the first dielectric layer in a higher ratio than in a boundary between the intermediate layer and the second dielectric layer, a ratio of the component that is not contained in the second dielectric layer and is contained only in the first dielectric layer decreasing from a side of the first dielectric layer to a side of the second dielectric layer;
- and
- a component that is not contained in the first dielectric layer and is contained only in the second dielectric layer in the boundary between the intermediate layer and the second dielectric layer in a higher ratio than in the boundary between the intermediate layer and the first dielectric layer, a ratio of the component that is not contained in the first dielectric layer and is contained only in the second dielectric layer decreasing from the side of the second dielectric layer to the side of the first dielectric layer.
