Abstract
A multilayer ceramic electronic component such as a multilayer ceramic capacitor capable of maintaining insulation properties even when a current is passed through the capacitor after an occurrence of a short-circuit due to, for example, a high voltage or a high current is provided. A multilayer ceramic electronic component including an element body 4 formed by laminating dielectric layers 10 and internal electrode layers 12 alternately. The internal electrode layers contains copper and/or silver as a main component. The dielectric voidage is lower than the internal electrode voidage.
Claims8
A multilayer ceramic electronic component comprising an element body including dielectric layers and internal electrode layers having different polarities laminated alternately, wherein
- the internal electrode layers contain copper and/or silver as a main component, and
- a dielectric voidage of the dielectric layers is lower than an internal electrode voidage of the internal electrode layers, the dielectric voidage indicates a proportion of a length of voids existing on a dielectric line segment with respect to a predetermined length of the dielectric line segment passing through a thickness-wise center of a freely selected layer of the dielectric layers and extending along a longitudinal direction of the dielectric layers, and the internal electrode voidage indicates a proportion of a length of voids existing on an internal electrode line segment with respect to a predetermined length of the internal electrode line segment passing through a substantially thickness-wise center of a freely selected layer of the internal electrode layers and extending in a longitudinal direction of the internal electrode layers.
