ABSTRACT:
A piezoelectric/electrostrictive film type device including a thin substrate made of ceramic and a piezoelectric/electrostrictive operating portion disposed on the substrate and constituted by successively laminating a lower electrode film, a piezoelectric/electrostrictive film containing a large number of crystal particles constituted of a piezoelectric/electrostrictive composition, and an upper electrode film. The piezoelectric/electrostrictive composition contains one or more alkali metal elements selected from the group consisting of lithium, potassium, and sodium, and one or more metal elements selected from the group consisting of niobium, tantalum, antimony, and silver. Circle equivalent diameters of 90% or more of the large number of crystal particles are in a range of 0.3 to 50 μm.
