发明名称 MONOLITHIC CERAMIC CAPACITOR ARRAY
摘要 PROBLEM TO BE SOLVED: To enlarge the range of use or application, by causing the area of effective overlap portions of internal electrode patterns connected to one external electrode and corresponding internal electrode patterns connected to the other external electrode to differ from one another. SOLUTION: A dielectric material 6 made of BaTiO3 , or the like is molded on a dielectric ceramic sheet, and internal electrodes 2a, 2b are printed on the sheet by a screen printing method. In this case, using a screen mask in which the area of a printing pattern to be used is varied, one internal electrode pattern 2a and the other internal electrode pattern 2b are printed. Thus, after a predetermined numlrer of intenal electrodes are stacked, heated, pressurized, and then cut into a size for four elements by using a blade, the internal electrodes are fired at 1000 to 100 deg.C. Then, end portions of the internal electrodes are exposed, coated with an external electrode 4, and fired at 800 deg.C. Thus, by varying values A1 to A4 of the area of an effective overlap portion in individual patterns C1 to C4 , a capacitance of C1≠C2≠C3≠C4 may be provided.
