<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated piezoelectric actuator wherein formation of external electrodes is enabled in mass production. <P>SOLUTION: After a surface of a first photogravure roll 21 on which a pattern is engraved is filled with insulator paste 23, it is transferred on a surface of a first transfer roll 22 which is rotated in contact with the first photogravure roll 21. By transferring the insulator paste on exposed ends of internal electrode layers of a ceramic lamination 1, insulating parts are arranged on every other exposed end of the internal electrode layers. In order to electrically connect all of the exposed ends of the internal electrodes which are not subjected to insulation coating at this time, conductive paste 33 is spread by using a second photogravure roll 31 and a second transfer roll 32. The external electrodes are formed in a single process of baking. <P>COPYRIGHT: (C)2004,JPO |
