摘要： A monolithic piezoelectric element includes a stack, and the stack includes a crack-forming conductive layer arranged to intentionally form a small crack in the stack. The small crack alleviates stress, thereby preventing the occurrence of a large crack that may extend to the piezoelectrically active region.

摘要： A monolithic piezoelectric element includes an element assembly in which internal electrode layers and piezoelectric ceramic layers are laminated alternately. The internal electrode layers contain an Ag—Pd alloy, which has an Ag content of 85 percent by weight or more as a primary component, a metal element having a valence of at least one of pentavalence or hexavalence. The piezoelectric ceramic layers contain a composite oxide represented by Pb(Ti,Zr)O3 as a primary component, a part of Ag contained in the internal electrode layers is almost uniformly diffused therein and, the metal element is diffused in the form of a metal oxide in such a way that the concentration is reduced with decreasing proximity to the internal electrode layers. In this manner, a monolithic piezoelectric element having a desired large piezoelectric constant can be obtained without inviting an increase in cost even when a firing treatment is conducted at low temperatures.

摘要： A piezoelectric element contains a piezoelectric ceramic body having a layered perovskite structure, and has the C axis selected and oriented in the thickness direction. In the piezoelectric ceramic body, line shaped electrodes are formed perpendicular to the C axis selected and oriented. The electrodes exposed at both of the end faces of the piezoelectric ceramic body are covered with conductive materials and insulation materials. The piezoelectric ceramic body is polarized in the opposite directions on both of the sides of electrodes arranged in the width direction.
