摘要： A flow path formation substrate to which a nozzle plate having a plurality of nozzles is mounted includes a shared supply path shared in liquid supply to a nozzle, an individual supply path branching off from the shared supply path and leading to a pressure chamber per nozzle, an individual recovery path including a communication flow path per nozzle, through which the nozzle and the pressure chamber communicate with each other, and a shared recovery path into which a plurality of individual recovery paths merge and which is shared in liquid recovery from the nozzles. A conduction unit electrically coupled through a lead electrode to a pressure generator causing a pressure of the pressure chamber to vary is located at a position where the conduction unit overlaps with a flow path area of at least one individual flow path of the individual supply path or the individual recovery path in a plan view from a lamination direction in which the nozzle plate and the flow path formation substrate are laminated.

摘要： A liquid ejection head includes a flow path substrate, a first plate, and a second plate. A first plate includes a nozzle for ejecting a liquid. A flow path substrate includes a first communication path which passes through a flow path substrate in a thickness direction and has an opening on each of a first plate side and a second plate side, and a second communication path communicating with an opening on a first plate side of a first communication path at a first plate side and extending on the second plate side. A pressure chamber communicating with a first communication path and a first flow path through which a liquid flows into a pressure chamber are formed by a part of a second plate and a part of a flow path substrate. A second plate is provided with a pressure generation portion for deforming a part of a second plate facing a pressure chamber. A second communication path communicates with a second flow path through which a liquid flows.
