    • There is provided a liquid jetting apparatus which includes: a liquid jetting head including a channel unit and a piezoelectric actuator, an elastic deformation layer arranged on the piezoelectric actuator, a plurality of head-side contact points arranged on the elastic deformation layer, a substrate arranged to face a surface of the liquid jetting head, a plurality of substrate-side contact points arranged on the substrate, and a fixing member fixing the liquid jetting head and the substrate. When the fixing member fixes the liquid jetting head and the substrate, a portion of the elastic deformation layer, on which the head-side contact points are arranged, is sandwiched by the piezoelectric actuator and the substrate to undergo elastic deformation. The elastic deformation layer is configured to press the plurality of head-side contact points onto the substrate-side contact points by a force arising from a tendency to restore a state before elastic deformation.
    • 提供了一种液体喷射装置,其包括:液体喷射头,包括通道单元和压电致动器,布置在压电致动器上的弹性变形层,布置在弹性变形层上的多个头侧接触点,基底 布置成面对液体喷射头的表面,布置在基板上的多个基板侧接触点和固定液体喷射头和基板的固定构件。 当固定构件固定液体喷射头和基板时,布置有头侧接触点的弹性变形层的一部分被压电致动器和基板夹持以进行弹性变形。 弹性变形层被构造成通过在弹性变形之前恢复状态的倾向产生的力将多个头侧接触点按压到基板侧接触点。
