Abstract

The present invention provides a ceramic electronic component (10), in which conductor patterns (3, 4) are arranged inside a laminate (1) on which a multilayer ceramic layer (2) is laminated, and on the left and right sides of the laminate (1) External electrodes (5, 6) electrically connected to the conductor patterns (3, 4) are formed on the end faces, wherein dummy electrodes (5, 6) are embedded under the extensions (51, 61) of the external electrodes (5, 6) via a ceramic layer (2). electrodes (3b, 4b), and via one or two of the ceramic layers (2) present between the dummy electrodes (3b, 4b) and the extensions (51, 61) of the external electrodes (5, 6) Metal particles M connect both. The peeling of the external electrodes (5, 6) can be effectively prevented by a simple and inexpensive method.

Description

technical field [0001] The present invention relates to ceramic electronic parts and a method of manufacturing the same. Background technique [0002] As a typical ceramic electronic part, a ceramic capacitor is used for the explanation. [0003] Figure 6 It is a sectional view showing a conventional ceramic capacitor. [0004] exist Figure 6 In the ceramic capacitor 30 , internal electrodes 33 and 34 are interposed between adjacent dielectric layers 32 inside a laminated body 31 in which a plurality of ceramic dielectric layers 32 are stacked. At the same time, the external electrodes 35 and 36 electrically connected to the ends of the internal electrodes 33 and 34 are formed on the end faces of the laminated body 31 so that the four sides of the external electrodes 35 and 36 extend on the four side surfaces of the laminated body 31. . [0005] According to the ceramic capacitor 30 described above, the external electrodes 35 and 36 contain a metal component and a glass...
