Abstract
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.
