Description
【発明の詳細な説明】 産業上の利用分野 本発明は積層セラミックコンデンサに関する。[Detailed description of the invention] Industrial applications The present invention relates to a multilayer ceramic capacitor.
従来の技術
従来の積層セラミックコンデンサは、セラミックシート
上にスクリーン印刷により内部電極を形成していた。BACKGROUND OF THE INVENTION Conventional multilayer ceramic capacitors have internal electrodes formed on ceramic sheets by screen printing.
発明が解決しようとする課題

ことを目的とするものである。Problems to be Solved by the Invention In the above-mentioned conventional technology, since the printed surface of the internal electrode is smooth, there is a difference in the shrinkage rate between the internal electrode and the ceramic sheet when firing the ceramic sheet and the internal electrode. During this period, a delamination phenomenon occurred, which caused a fatal problem in the characteristics of the multilayer ceramic capacitor. Therefore, an object of the present invention is to prevent the above-mentioned peeling.
課題を解決するための手段

The internal electrode @2 in Fig. 1 has a mesh shape as shown in Fig. 2, so there is a hole in the upper part of the hole 3. The lower ceramic sheet 1 is not wedged in, and as a result, the adhesive force is strengthened.
