PURPOSE:To eliminate the need for finishing and correction processes, and to facilitate and simplify preparation by a method wherein an external leading-out terminal assembly is thermocompression-bonded and connected, insulating resin powder is attached through electrostatic coating, one part of the powder is sucked and removed and the powder is melted and cured. CONSTITUTION:A plurality of ceramic electrostriction material layers 3, on one surfaces of which internal electrode layers 2 are formed respectively, are laminated, the end sections of the electrodes 2 exposed on both side faces as piezoelectric elements 1 are coated alternately with insulating layers 4 at every one layer, and external electrode layers 5 connecting the end sections of the electrodes 2 exposed are shaped. External leading-out terminal assemblies 6a, 6b are contact-bonded and connected at the central section of the layers 5 by the pushing of a heated pressure bar, both surfaces of the elements are masked with mask jigs, an outer circumference is coated electrostatically with resin powder to form a resin layer 9, and the resin powder of the terminal assemblies 6a, 6b is sucked and removed. When the layer 9 is melted and cured in a furnace, resin powder hardly adheres on the mask jigs, and ceramic laminate electronic components such as the piezoelectric elements are prepared easily and simply without finishing and correction processes. |
