摘要： In order to prevent the ingress of moisture into a void section of a component main body of a ceramic electronic component, at least the component main body of the ceramic electronic component is provided with water repellency using a water repellent agent. The water repellent agent is dissolved in a supercritical fluid such as, a supercritical CO2 fluid, as a solvent to provide at least the component main body with water repellency. After providing the water repellency, the water repellent agent on the outer surface of the component main body is removed. As the water repellent agent, a silane coupling agent may be used.

摘要： A method for manufacturing a laminated electronic component is performed such that a water-repellent agent is applied to end surfaces at which ends of internal electrodes are exposed so as to be filled in spaces along interfaces between insulating layers and the internal electrodes. Subsequently, an abrading step is performed such that the internal electrodes are sufficiently exposed at the end surfaces and an excess water-repellent agent is removed therefrom to enable plating films to be directly formed on the end surfaces.

摘要： Provided is a method for producing a ceramic body, which is capable of preventing the ingress of moisture into a void between a conductor and the ceramic body more effectively in the ceramic body including the conductor therein. Ingress of a supercritical fluid containing an oxide sol precursor is achieved into a void between an internal electrode layer and a ceramic laminate. After that, the oxide sol is turned into a gel, and subjected to a heat treatment, thereby filling the void between the internal electrode layer and the ceramic laminate with an oxide.
