Problems solved by technology

[0004] However, in the case of printing ceramic paste for absorption steps around internal electrodes, it is necessary to print the ceramic paste with an accurate printing pattern, requiring high printing accuracy
Adding such a process complicates the manufacturing process
[0005] In addition, in the case of printing ceramic paste for absorption steps around the internal electrodes, there is a problem of damage to the ceramic green sheet

Embodiment Construction

[0031]

[0032] figure 1 It is a sectional view showing an embodiment of the multilayer ceramic capacitor according to the present invention. figure 2 is along figure 1 A sectional view of the 2-2 line. As shown in the figure, the multilayer ceramic capacitor according to the present invention has a ceramic base 1 and n-layer internal electrodes 21 to 2n.

[0033] The ceramic base 1 is made of, for example, a dielectric material mainly composed of barium titanate. The ceramic base 1 is a shape defined by a length direction L, a width direction W, and a thickness direction T. Specifically, the ceramic base 1 has a substantially rectangular parallelepiped shape having a length direction L, a width direction W, and a thickness direction T. As shown in FIG. Regarding the dimensions of the ceramic base 1, numerical values ​​thereof are exemplified as follows. The length dimension, width dimension and thickness dimension are 3.2mm, 1.6mm and 1.6mm, respectively.

Abstract

A laminated ceramic capacitor includes a ceramic substrate and a plurality of internal electrodes. The ceramic substrate is of a shape defined by length, width and thickness directions. The internal electrodes are stacked one over another within the ceramic substrate at spaced intervals in the thickness direction and alternately led out to opposite ends of the ceramic substrate in the length direction. The ceramic substrate has opposite surfaces in the thickness direction, one of which is planar. In the laminated ceramic capacitor, 1 H01G 4 / 30 H01G 4 / 12 5 19 1 2006 / 5 / 24 1870190 2006 / 11 / 29 000000000 TDK Corp. Japan Kojima Tatsuya hu jianxin 72002 NTD Patent & Trademark Agency Ltd.

Description

technical field [0001] The present invention relates to a multilayer ceramic capacitor and a method of manufacturing the same. Background technique [0002] In general, a multilayer ceramic capacitor has a structure in which a plurality of internal electrodes are laminated with ceramic layers interposed therebetween, and are alternately led out to both ends of the ceramic substrate. In such a multilayer ceramic capacitor, between the end portion and the central portion of the ceramic base, that is, between the portion where the internal electrodes and blank areas are alternately arranged and the portion where only the internal electrodes appear, viewed from the lamination direction, A step difference (height difference) is formed depending on the presence or absence of the internal electrodes. This step difference causes a dimensional error of the ceramic base body, resulting in defective assembly when mounting a multilayer ceramic capacitor. [0003] As a technique for so...
