摘要： A piezoelectric/electrostrictive membrane sensor is provided, wherein a piezoelectric/electrostrictive body contains an alkali metal or an alkaline earth metal, and a sulfide and the main component of terminal electrodes are contained near the surface of the piezoelectric/electrostrictive body. A voltage equal to or higher than a withstand voltage is hardly applied to the piezoelectric/electrostrictive body, and consequently, the sensor is prevented from dielectric breakdown. In addition, the sensor is hardly electrostatically charged, and thus prevented from electrostatic discharge damage and attraction of dust, dirt or the like.

摘要： A piezoelectric/electrostrictive element with improved moisture resistance while having less degradation in its piezoelectric/electrostrictive properties and a method of manufacturing such a piezoelectric/electrostrictive element are provided. A laminated vibrator of a piezoelectric/electrostrictive element has a structure in which an electrode film, a piezoelectric/electrostrictive film, another electrode film, another piezoelectric/electrostrictive film, and another electrode film are laminated one above the other. In the manufacture of the piezoelectric/electrostrictive element, the laminated vibrator and a counter electrode are immersed in an electrodeposition coating fluid containing a coating component so that the electrodeposition coating fluid is brought into contact with the surfaces of the laminated vibrator and the counter electrode. Thereafter, voltage is applied between an internal electrode film and the counter electrode to induce electrophoresis of the coating component toward a surface-exposed defect, whereby the coating material is selectively electrodeposited on the surface-exposed defect.
