    • A liquid ejecting head has a piezoelectric element with a first electrode, a piezoelectric layer, and a second electrode. The liquid ejecting head causes pressure changes in a pressure generating chamber communicating with a nozzle opening. The piezoelectric layer has a perovskite structure and is preferentially orientated in a (100) plane. A method for producing the liquid ejecting head includes polarizing the piezoelectric layer by applying an electric field having energy higher than energy required for converting the polarization direction in the direction to the direction and lower than energy required for converting the polarization direction in the direction to the direction when the electric field to be applied to the piezoelectric layer is in the direction vertical to a plane on which the second electrode is provided.
    • 液体喷射头具有带有第一电极,压电层和第二电极的压电元件。 液体喷射头在与喷嘴开口连通的压力发生室中引起压力变化。 压电层具有钙钛矿结构,并且优选地在(100)平面中取向。 一种液体喷射头的制造方法,其特征在于,通过将<111>方向的偏振方向转换成<110>方向所需的能量的能量高于低于转换极化所需的能量, 当施加到压电层的电场处于与设置有第二电极的平面垂直的<001>方向时,<111>方向朝向<001>方向的方向。

    • A liquid ejecting head includes a flow channel forming substrate having a pressure generation chamber communicating with a nozzle opening and arranged in parallel along a lateral direction. A piezoelectric element is provided on one surface of the flow channel forming substrate in correspondence to the pressure generation chamber, and has a first electrode, a piezoelectric layer provided on the first electrode and a second electrode provided on the piezoelectric layer. In a direction intersecting with the arrangement direction of the pressure generation chamber, in boundaries between an active section that is a substantial driving section and an inactive section that is not a substantial driving section of the piezoelectric layer of the first electrode, an opening group is provided including at least one opening in the active section and the inactive section.
    • 液体喷射头包括具有与喷嘴开口连通并沿着横向平行设置的压力产生室的流路形成基板。 压电元件设置在对应于压力产生室的流道形成基板的一个表面上,并且具有第一电极,设置在第一电极上的压电层和设置在压电层上的第二电极。 在与压力产生室的排列方向相交的方向上,在作为实质的驱动部分的有效部分和不是第一电极的压电层的实质驱动部分的非活动部分之间的边界中,开口组是 提供在活动部分和非活动部分中包括至少一个开口。
