Abstract
Disclosed is a piezoelectric/electrostrictive membrane sensor wherein the main component of terminal electrodes is contained in the vicinity of the surface of a piezoelectric/electrostrictive body. The membrane sensor is hardly electrostatically charged and thus prevented from electrostatic discharge damage and/or the attraction of dust, dirt or the like.
