A liquid ejecting head includes a flow passage unit, a vibrator unit, a case and a reinforcing plate. The flow passage unit includes a liquid flow passage and a diaphragm portion. The liquid flow passage includes a pressure chamber that communicates with a nozzle opening. The diaphragm portion is formed at a portion corresponding to the pressure chamber and varies a volume of the pressure chamber. The vibrator unit includes a piezoelectric vibrator that is bonded to the diaphragm portion. The piezoelectric vibrator displaces the diaphragm portion. The case has an accommodation chamber formed therein to accommodate the vibrator unit. The reinforcing plate has an insertion opening portion that is formed at a position corresponding to the diaphragm portion and through which a free end portion of the piezoelectric vibrator is insertable. The reinforcing plate is interposed between the case and the flow passage unit.
