    摘要： A piezoelectric element includes a first electrode film; a piezoelectric layered film including a first piezoelectric thin film formed on the first electrode film and a second piezoelectric thin film formed on the first piezoelectric thin film; and a second electrode film formed on the second piezoelectric thin film. Each of the first and second piezoelectric thin films is an aggregate of columnar grains grown unidirectionally along the thickness direction of the piezoelectric layered film. The Pb content of the first piezoelectric thin film is smaller than the Pb content of the second piezoelectric thin film. A columnar grain of the second piezoelectric thin film has a larger average cross-sectional diameter than an average cross-sectional diameter of a columnar grain of the first piezoelectric thin film. A ratio of the thickness of the piezoelectric layered film to the average cross-sectional diameter of the second piezoelectric thin film is not less than 20 and not more than 60.

    摘要： First, a first electrode layer 4, a piezoelectric layer 5, a second electrode layer 6 and an oscillation layer 7 are stacked in this order over one surface of a silicon substrate 1. Next, an ink chamber partition 8 and a nozzle plate 11 are stacked over the oscillation layer 7. Subsequently, the silicon substrate 1 is ground away to a predetermined thickness from a surface thereof opposite to the first electrode layer 4, and then a remnant silicon substrate 13 is dry etched away. Thereafter, the first electrode layer 4 is patterned to form a plurality of inkjet mechanisms 2, 2, . . . . Finally, the plurality of inkjet mechanisms 2, 2, . . . are divided to simultaneously fabricate a plurality of inkjet heads 3, 3, . . . .
