An electrostrictive effect element has a laminated-structure formed by a plurality of electrostrictive ceramic members and a plurality of internal electrode conductive layers which are stacked alternatingly. The electrostrictive effect element has, on each of the opposite side surfaces of the laminated-structure, an external electrode conductive layer which is formed by a plurality of land conductors made of sintered-type conductive paste for interconnecting the exposed internal electrode conductive layers not covered by glass insulation layers, and a belt-like conductor made of resin hardening-type conductive paste for interconnecting the plurality of land conductors. Silver diffusion into the glass insulation layers can be avoided while maintaining low contact resistance between the external electrode conductive layer and the internal electrode conductive layers. A reliable electrostrictive effect element with excellent electrical characteristics, which does not suffer from any insulation deterioration to be caused by diffusion of silver into the glass insulation layers and which can be used satisfactorily in pulse-signal used applications is realized.
