摘要:
To obtain a plurality of laminated ceramic capacitors, in cutting a laminated body (14) formed of a plurality of ceramic green sheets (11) formed on their surfaces with electrically conductive films (12) to serve as internal electrodes, cutting is effected in such a manner that the electrically conductive films (12) are exposed on lateral surfaces (17), which are the surfaces that are not formed with external electrodes (22, 23). Then ceramic slurry (18) is applied to the lateral surfaces (17), thereby preventing the exposure of the internal electrodes (12) on the lateral surfaces (17) where connection to the external eletrodes (22, 23) is not desired. The invention makes effective use of the entire width of the ceramic layers forming the cut laminated body (16) so as to obtain electrostatic capacity in a space-efficient manner.
