Liquid ejecting head and liquid ejecting apparatus

摘要

A liquid ejecting apparatus is provided with an actuator substrate on which a piezoelectric actuator that generates a pressure change in a pressure generation chamber, which is in communication with a nozzle opening that ejects a liquid, is provided. The liquid ejecting head is provided with lead-out wiring that is led out from the piezoelectric actuator to the top of the actuator substrate, the lead-out wiring is provided with an adhesive layer that is provided on an actuator substrate side, and a conductive layer that is provided on a side of the adhesive layer which is opposite the actuator substrate, and the adhesive layer has a width that is narrower than the conductive layer in at least a parallel arrangement direction of the lead-out wiring.
