摘要：PURPOSE:To prevent the deterioration of characteristics when the surface of an outer electrode is covered by an electroplating method, by constituting a plating layer as a three-layered structure by using three kinds of specified metals of specified thickness. CONSTITUTION:Ceramic element bodies 10 and outer electrodes 11, which are formed on the outer surfaces of the element bodies 10 and have baked electrode layers 12 containing noble metal and glass frit, are provided. A ceramic capacitor has plating layers formed by using at least one kind out of Ni, Cu, Sn, and Sn/Pb, on the surface of the baked electrode layer 12. A Cu-plated layer 13, an Ni-plated layer 14, and an Sn or Sn/Pb-plated layer 15 are formed in this order on the surface of the baked electrode layer 12. The thickness of the Cu-plated layer is in the range of 3-30mum. the thickness of the Ni-plated layer is in the range of 1-5mum. and the thickness of the Sn or Sn/Pb-plated layer 15 is in the range of 3-30mum.
