Problems solved by technology

[0013] However, if the amount of inorganic particles contained in the conductive paste for via-hole conductors is large, the conduction resistance of the via-hole conductors 108 and 109 may increase, or the above-mentioned via-hole conductors 108 and 109 may be disconnected.
Therefore, the amount of inorganic particles contained in the conductive paste for via-hole conductors needs to be suppressed to a small amount. The effect of shifting the sintering star

Abstract

The present invention relates to a ceramic electronic component wherein via conductors that are embedded in through holes of dielectric layers formed from a sintered body of ceramic particles are made by firing a electrically conductive paste for via conductor that contains inorganic particles made of the same material as the ceramic particles that constitute the dielectric layer and having an average particle diameter smaller than that of the ceramic particles, and a method for manufacturing the same. According to the present invention, such a ceramic electronic component can be provided that the via conductors and the internal electrodes are electrically connected with each other satisfactorily without voids generated therein.

Description

technical field [0001] The present invention relates to a ceramic electronic component including a dielectric layer formed of a sintered body of ceramic particles and provided with a through hole, a via conductor embedded in the through hole of the dielectric layer, and a method for manufacturing the ceramic electronic component. Background technique [0002] In recent years, in multilayer ceramic capacitors and the like, especially ceramic electronic components having a laminated structure with two or more laminated dielectric layers, in order to reduce the equivalent series resistance or equivalent series Inductance, and the use of a structure in which the above-mentioned conductor wiring is electrically connected to a via conductor penetrating through the stacking direction of the ceramic electronic component is gradually increasing. [0003] Figure 9 It is a cross-sectional view showing an example of the multilayer ceramic capacitor 101 having the above structure. refe...
