PURPOSE:To increase the adhesion strength by a method wherein ceramics material sintered at a low temperature is used as internal electrodes beside metallic constituents, in an electrostrictive effect element having the ceramics material showing electrostrictive effect and the internal electrodes. CONSTITUTION:The paste which turns the internal electrode 2 is printed over a film of the electrostrictive material 1 composed of lead magnesiumniobate and lead titanate by a screen printing method. As the material for the electrode 2, the mixture of the platinum paste and ceramics powder is used. For this powder, that which can be sintered at a temperature lower than that for the electrostrictive material 1 is used. Next, the material 1 whereon the electrode 2 is printed is instered. Then, the electrodes 2 are connected by lead wires 3, and thus the electrode terminals A and B are taken out. |
