Title:
CERAMIC ELECTRONIC COMPONENT AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2023143031
Kind Code:
A
Abstract:
To provide a ceramic electronic component capable of improving the moisture resistance reliability thereof, and a manufacturing method thereof.SOLUTION: A ceramic electronic component includes: an elementary body including a plurality of dielectric layers and a plurality of internal electrode layers laminated via the dielectric layers and provided to face each other while one end of each internal electrode is exposed; a ground layer that is provided on an end face of the elementary body, the end face being an end in a direction where the internal electrode layers are extended, and that comes into contact with the one end of each of the internal electrode layers, the ground layer containing Cu as main components; a Ni plating layer formed on the ground layer; and metal oxide particles disposed on a surface of the ground layer on a Ni plating layer side or on a surface of a metal layer disposed between the ground layer and the Ni plating layer on the Ni plating layer side. The metal oxide particles are an oxide of a metal other than Cu when being disposed on the surface of the ground layer, while the metal oxide particles are an oxide of a metal other than a main component metal of the metal layer when being disposed on the surface of the metal layer.SELECTED DRAWING: Figure 4
