Liquid ejecting head and manufacturing method of liquid ejecting head

A manufacturing method of a liquid ejecting head which includes

• a nozzle which ejects a liquid,
• a pressure chamber, a portion of which is partitioned by a flexible diaphragm and which communicates with the nozzle,
• an actuator which is laminated on an opposite side of the diaphragm from the pressure chamber and changes a pressure within the pressure chamber,
• a reservoir which communicates with the pressure chamber, and
• a valve mechanism which is provided in a region which is distanced from a region in which the actuator of the diaphragm is laminated, the method comprising:
• forming an opening in a region which is distanced from a region of the diaphragm in which the actuator is laminated;
• forming a valve receiving body in a region which overlaps the opening of the diaphragm in the reservoir side to interpose a thin film therebetween;
• and
• removing at least the thin film between the opening and the valve receiving body.
