摘要:
A flow path forming substrate on which a nozzle plate including a plurality of nozzles is mounted forms a supply flow path from a shared supply path shared for liquid supply to the plurality of nozzles, and an individual supply path branching from the shared supply path and leading to a pressure chamber for each of the nozzles, and forms a collecting flow path from an individual collecting path for each of the nozzles communicated with the communication flow path for each of the nozzles communicating with the nozzles and pressure chambers, and a shared collecting path shared for liquid collection from the plurality of nozzles by joining to the individual collecting path. The shared supply path is liquid-tightly closed by a supply-side flexible plate having flexibility, and the collecting flow path is liquid-tightly closed by a collecting-side flexible plate having flexibility over a flow path area.
