Abstract:
1. A liquid droplet jetting apparatus which jets droplets of liquid, comprising: a liquid droplet jetting head which jets liquid droplets when an actuator having a plurality of energy generating portions is driven; and a wiring member via which a drive signal is outputted to a surface electrode formed in the actuator, the wiring member including an insulative substrate, a wire provided on one surface of the substrate, and a covering member having an insulating property and covering the wire, the wire having an electrode land which is stacked on the surface electrode to be connected to the surface electrode, the covering member having a first covering layer in which a first opening to expose the electrode land therein is formed and a second covering layer having a second opening communicating with the first opening and covering the first covering layer, wherein the second opening is formed so as to face the surface electrode; a circumference of the second opening is greater than a circumference of the first opening; an area of the surface electrode is greater than an exposure area of the electrode land; the surface electrode is projected partially toward an outside of the electrode land; and the surface electrode and the electrode land are connected in a state that an electroconductive material is interposed between the surface electrode and the electrode land through the first opening and the second opening.
