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.
