摘要： Internal electrode layers are superimposed in a dielectric substrate 1 at intervals. Step absorption layers are respectively provided on lateral sides of the internal electrode layers. A side portion of the internal electrode layer forms an inclined surface, and the step absorption layer is superimposed so as to partially overlap the inclined surface of the internal electrode layer. This is also applied to the other internal electrode layers and step absorption layers.
摘要翻译： 内部电极层间隔叠加在电介质基板1中。 在内侧电极层的侧面分别设有阶梯型吸收层。 内部电极层的侧部形成倾斜面，并且台阶吸收层重叠以与内部电极层的倾斜面部分重叠。 这也适用于其它内部电极层和阶梯吸收层。

摘要： A multilayer electronic component comprises an inner multilayer portion and a pair of outer multilayer portions. The inner multilayer portion includes a plurality of first ceramic layers and a plurality of internal circuit element conductors which are alternately laminated and contain a glass component. A component amount ratio of an amount of the glass component in the second ceramic layers to an amount of a principal component of the second ceramic layers is larger than a component amount ratio of an amount of the glass component in the first ceramic layers to an amount of a principal component of the first ceramic layers.
