    摘要: A piezoelectric/electrostrictive device is provided in which a connection plate whose one end in the longitudinal direction is held by two diaphragms and whose other end is held by two other diaphragms is spanned between bottoms of faced concave portions formed on a substrate, and piezoelectric elements are arranged on at least a part of at least one-side plane surface of each of the diaphragms, and the diaphragms are connected with the sides of the concave portions in at least the direction for the diaphragms to hold the connection plate, and a fixing plate is connected to the connection plate so that the longitudinal direction of the fixing plate becomes parallel with the direction for the diaphragms to hold the connection plate. A displacement of the fixing plate generated by applying a voltage to the piezoelectric element is utilized or an electromotive force of the piezoelectric element based on a displacement of the fixing plate is utilized. The piezoelectric/electrostrictive device is preferably used as a positioning- or angle-adjustment mechanism of an optical unit or precision unit, a vibrator or resonator for communication or motive power, an oscillator, a discriminator, an ultrasonic sensor, or an acceleration sensor because the device is able to convert electric energy into mechanical energy such as a mechanical displacement, force, or vibration and vice versa.
