摘要： A ceramic electronic component having a ceramic member into which no plating intrudes, and a method of producing the ceramic electronic component by which the ceramic electronic component can be easily produced are provided. The ceramic electronic component contains a ceramic member, and terminal electrodes formed on both of end-faces of the ceramic member. Each terminal electrode comprises an external electrode, and a plating coat formed thereon. To produce the ceramic electronic component, the ceramic member having the external electrodes are dipped into a water-repelling agent, dried, and plated. The water-repelling agent contains a functional group which is readily adsorbed to the external electrodes and a hydrophobic functional group.
