Abstract
Official abstract text for this publication.
A liquid ejecting head includes a pressure element that applies a pressure to a pressure chamber which communicates with a nozzle which ejects a liquid, and a lead electrode that is joined to a wiring substrate which supplies a driving signal which drives the piezoelectric element, and the pressure element, in which a surface of the lead electrode on the wiring substrate side in a connection region between the lead electrode and the wiring substrate becomes a concavo-convex surface, in which the lead electrode and the wiring substrate are fixed to each other at a periphery of the connection region and at least one portion of a concave portion of the concavo-convex surface of the lead electrode with a non-conductive paste, and in which the lead electrode and the wiring substrate are electrically connected to each other at a convex portion of the concavo-convex surface of the lead electrode on which the non-conductive paste is not present.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid ejecting head for ejecting a liquid, the liquid ejecting head comprising: a pressure element for ejecting the liquid from a nozzle; a lead electrode for transmitting a driving signal to the pressure element; and a wiring substrate for transmitting the driving signal to the lead electrode; wherein the lead electrode and the wiring substrate are connected at a junction region, the lead electrode has a concavo-convex surface made of a concave p…
