LAMINATED CERAMIC CAPACITOR

摘要

PURPOSE:To prevent a delamination from being caused by a method wherein a paste in which a ceramic pulverulent body coated with a copper layer has been kneaded in an organic vehicle is used as an internal electrode. CONSTITUTION:A ceramic composed of 95% or more BaTiO3 is used as a ceramic dielectric powder; and a ceramic dielectric 12 is produced. A paste is printed and coated on its surface; and a dielectric sheet 14 in which an internal electrode 13 is formed is obtained. A ceramic dielectric powder 15 whose average particle size is 1mum is used as the paste. The following are used as the internal electrode 13: a copper-layer coating ceramic powder 7 coated with a copper layer 16 having an average thickness of about 0.05mum; and a paste 18 whose viscosity is adjusted by adding a solvent after it is kneaded well with an organic vehicle. When the dielectric ceramic powder coated with the copper layer is used, the relative volume of copper is reduced. As a result, it is possible to suppress a molten expansion amount and to prevent a delamination defect from being caused.
