发明名称 MULTILAYER CERAMIC CAPACITOR AND MANUFACTURE THEREOF
摘要 PROBLEM TO BE SOLVED: To solve an interlayer separation, which is generated in keeping with a thinner filming of a multilayer ceramic capacitor, by a method wherein the thickness of the lead-out electrode parts of the internal electrode layer of the multilayer ceramic capacitor and the thickness of the capacitor electrode part of the internal electrode layer are respectively made thin in the extent of a specified numerical value. SOLUTION: A 10-μm thick ceramic green sheet consisting of a lead-containing composite perovskite ceramic derivative is made. A conductive paste containing metallic powder, which contains silver and palladium as its main component, is screen- printed on this green sheet and this green sheet is used as an internal electrode layer afterwards. At this time, the thickness of lead-out electrode parts 21 of the internal electrode layer is formed in 0.8 to 2.0μm and the thickness of a capacitor electrode part 22 of the internal electrode layer is formed in 0.4 to 1.2μm. When the thickness of electrodes of the lead-out electrode parts 21 is thin by the result of the observation of the section of a capacitance defective, the contact of the parts 21 with the electrode layer is weakened and the connection of the parts 21 with external electrodes 4 is cut by a stress due to a piezoelectric phenomenon. As a result, it is understood that the meshes of capacity electrode parts 32 of a screen 3 can not be manufactured with a normal 600-mesh screen.
