Abstract
A manufacturing method for a piezoelectric/electrostrictive film type element and a film constituting a laminated vibrator made of laminations of an electrode film and a piezoelectric/electrostrictive film in a plane position. The piezoelectric/electrostrictive film type element includes a substrate, a lower electrode film provided on the substrate, and a laminated vibrator made of laminations of a piezoelectric/electrostrictive film and an upper electrode film. The lower electrode film is formed by a photolithography method with the substrate, where a cavity is filled with a light shielding agent, as a mask. Thereafter, the piezoelectric/electrostrictive film is formed by electrophoresis of powder of a piezoelectric/electrostrictive material toward the lower electrode film, and the upper electrode film is formed by the photolithography method with the piezoelectric/electrostrictive film as a mask. The piezoelectric/electrostrictive film may be formed by the photolithography method with the lower electrode film as a mask.
