    摘要: Oxygen defect of PZT can be suppressed from being generated because a temperature of a piezoelectric layer containing the PZT when a first layer of an upper electrode is formed is equal to or lower than 250° C. If the first layer containing Ir is formed on the piezoelectric layer in a state where the piezoelectric layer as a substrate is at the temperature of equal to or lower than 250° C., a compression stress is generated on the first layer. Then, a second layer having a tensile stress is formed on the first layer on which the compression stress is generated. This makes it possible to eliminate deflection on an entire piezoelectric element. Accordingly, since an initial deflection is small, reduction in the deflection amount of the piezoelectric element can be suppressed. Therefore, an actuator apparatus in which reduction in a displacement amount can be suppressed can be obtained.

    摘要翻译: 当形成上电极的第一层时,含有PZT的压电层的温度等于或低于250℃,可以抑制PZT的氧缺陷的产生。如果含有Ir的第一层形成在 在作为基板的压电体层的温度处于250℃以下的状态下的压电层,在第一层上产生压缩应力。 然后,在产生压缩应力的第一层上形成具有拉伸应力的第二层。 这使得可以消除整个压电元件上的偏转。 因此,由于初始偏转小,因此可以抑制压电元件的偏转量的减小。 因此,可以获得可以抑制位移量减小的致动器装置。
