A liquid-jet head has a passage-forming substrate with an individual path including a pressure-generating chamber communicating with a nozzle orifice which ejects a liquid. The head also has a pressure-generating element, a protection plate, a reservoir, a compliance plate, a through hole, an introducing path, and a flexible portion with flexibility in a region of the compliance plate, the region facing the reservoir, which region covers at least from a part facing the through hole to a part surrounding the introducing path.
