发明名称 Liquid ejecting head and liquid ejecting apparatus
摘要 A liquid ejecting head in which a flow path substrate having a communication hole communicating with a nozzle and a pressure chamber substrate having a space that is a pressure chamber are at least laminated includes: an actuator having an active section that is interposed between electrodes and applies pressure to the pressure chamber. The pressure chamber substrate has a first space positioned in a region corresponding to the active section and a second space positioned nearer to the nozzle than the first space and communicating with the first space among the spaces. The communication hole does not overlap with the first space and overlaps with at least a part of the second space in a lamination direction.
