Abstract:
A liquid ejecting head includes a channel unit having a plurality of pressure chambers respectively communicating with a plurality of nozzles opened to a nozzle formation surface, a plurality of reservoirs for supplying liquid to the plurality of the pressure chambers, and a plurality of compliance units formed by partitioning at least a part of the surface of each reservoir opposite to the nozzle formation surface by a film member; and a head case joined to a surface of the channel unit. A concave chamber formed by depressing a part of a surface joined to the channel unit in a side opposite to the reservoir and an atmosphere opening passage whose one end communicates with the concave chamber and the other end is opened to the atmosphere are formed at the head case. The concave chamber is formed in series over the compliance units.
