摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric/electrostrictive actuator using a piezoelectric/electrostrictive film that is excellent in accuracy of dimension and accuracy of worked shape. SOLUTION: This piezoelectric/electrostrictive actuator 10 is manufactured by forming a lower electrode 20 on the upper surface of a substrate 50 (B) and the piezoelectric/electrostrictive film 30 on the upper surface of the substrate 50 by applying or transferring piezoelectric/electrostrictive paste to the whole upper surface of the substrate 50 so as to cover the electrode 20 (C). Then a photoresist 100 is adhered to the upper surface of the film 30 (D) and exposed to light by photolithography by masking the photoresist 100 with a light shielding mask having a prescribed pattern. After the photoresist 100 is exposed, the unnecessary portion of the photoresist 100 is removed (E) and the unnecessary portion of the piezoelectric/electrostrictive film 30 is removed by sand blasting by using an abrasive (F). Finally, the remaining photoresist is removed (G) and an upper electrode 40 is formed on the remaining piezoelectric/ electrostrictive film 30 (H).
