A laminated body in which piezoelectric ceramic layers and internal electrode conductor layers are alternately laminated, and a tapered part of a conical hole is formed on both end faces of the laminated body in the direction in which electrostriction occurs, and the center of the tapered part is located to produce an electrostrictive effect. In an electrostrictive element mounting mechanism in which an electrostrictive effect element having a metal member arranged to coincide with a generation axis is attached to an electrostrictive effect element mounting member, a tapered part of a conical hole is provided in the mounting member. and a spherical object is held between a stress application point between a tapered part of the conical hole of the metal member and a tapered part of the conical hole of the mounting member. mechanism.
