A drive circuit for a two layer laminated electrostriction element which is formed by laminating two sheets of electrostrictive deflection elements at adjacent surfaces thereof, comprising: a first circuit for charging a first of said deflection elements by applying voltage thereto causing said first deflection element, and thereby said electrostriction element, to deflect in a first direction, a second circuit for discharging said first deflection element after said first circuit is deactivated and no longer applying voltage to said first deflection element and a third circuit for charging a second of said deflection elements, said second circuit being connected to said third circuit such that a part of the discharging current from said first of said deflection elements is coupled to said third circuit for charging said second deflection element thereby causing said second deflection element, and thereby said electrostriction element, to deflect in a direction opposite to the direction of deflection of said first deflection element.
