PURPOSE:To enable selective deposit of glass powder on the inner electrode exposure part of an end surface of an electrostriction material lamination with high reliability by a method wherein a voltage of polarity different from that of the electrified glass powder is impressed on an inner electrode on which electrodeposit glass powder is required, and a voltage of reverse polarity is impressed on the inner electrode on which you do not want to electrodeposit glass powder. CONSTITUTION:The positive of a main DC power source 33 is connected to an opposite electrode 31, and the negative is connected to a tentative outer electrode 12 of the assemblage of the inner electrodes on which glass is to be deposited; thereby, the glass powder becomes deposited on the inner electrode connected to the outer electrode 12 and on the ceramic in the periphery of the inner electrode by electric phoresis. The positive of an auxiliary DC power source 32 is connected to a tentative outer electrode 14 of the assemblage of the inner electrodes on which glass powder is not to be deposited, and the negative is connected to the negative of the main DC power source 33. Thereby, glass powder is repelled and does never deposit on the inner electrode not for deposit in the case of impressing a load by electric phoresis method. |
