摘要:
A liquid ejecting head which includes a flow passage forming substrate that has pressure generating chambers which communicate with nozzles capable of ejecting a liquid, pressure generating elements which apply pressure to the pressure generating chambers in order to eject the liquid from the nozzles, lead electrodes that supply electric signals to the pressure generating elements, wiring substrates that supply the electric signals to the lead electrodes, and a supporting member that supports the wiring substrates so as to raise the wiring substrates from a surface of the liquid ejecting head having the lead electrodes provided thereon.
