Abstract
A liquid ejecting apparatus may include a flow path forming substrate in which a pressure generation chamber which communicates with a nozzle opening that discharges liquid is formed and a communication plate which has a supply path that communicates with a manifold. A recess portion which configures at least a part of the manifold is open on a side opposite to the flow path forming substrate, on the communication plate. The supply path includes a discharge supply path which communicates with a discharge pressure generation chamber that discharges liquid from the nozzle opening, and a dummy supply path which communicates with a dummy pressure generation chamber that does not discharge liquid from the nozzle opening.
