Liquid ejecting head and liquid ejecting apparatus
Liquid ejecting head comprises a unit head bonded to a communication substrate. A plurality of liquid chamber forming portions are formed in the unit case, along a first direction at positions that are separated by a partition wall. A plurality of empty liquid chamber portions and supply-side communication paths are formed in the communication substrate. The supply-side communication paths include a common communication path formed in a opposite side with a thin thickness portion left in the surface side of the communication substrate, and individual communication paths. With a surface of the partition wall and a surface of the thin thickness portion bonded together, the empty liquid chamber forming portions and the empty liquid chamber portions communicate with each other so as to define a plurality of common liquid chambers.
