Abstract

PURPOSE: To prevent the penetration of moisture into a piezoelectric laminated body of this design so as to enhance it in resistance to an organic solvent or the like by a method wherein an insulating layer containing at least one of epoxy resin, silicone rubber, a thermally shrinkable tube, an adhesive agent is formed in close contact with the peripheral side face of two or more laminat ed piezoelectric plates which expand or shrink when a voltage is applied.
CONSTITUTION: A piezoelectric plate 1 expands or shrinks when a voltage is applied between lead wires 2. An insulating layer 3 is formed on the outer periphery of the piezoelectric plate 1 in a following process: first of all, the outer peripheral face of the piezoelectric plate 1 is adjusted in roughness and subjected to a treatment that the lead wires 2 are easily bonded; then, a degreasing treatment is carried out to the face concerned using a solvent such as trichlene or the like; and the face is dried up and then the insulating layer 3 is formed thereon through a potting method. Then, the insulating layer 3 is brought into close contact with a part of the piezoelectric plate 1 and the lead wires 2 through baking or curing. The insulating layer 3 is formed of epoxy resin, silicone rubber or the like. The periphery of the insulating layer 3 may as well be firmly coated with a thermally shrinkable tube 4.
