INKJET HEAD, INKJET RECORDING APPARATUS, LIQUID DROPLET EJECTING APPARATUS, AND IMAGE FORMING APPARATUS

摘要

An inkjet head is disclosed. In the inkjet head a vibrating plate is formed on a liquid chamber substrate on which multiple dedicated liquid chambers are aligned; a first insulating film and a second insulating film are formed between a dedicated electrode wiring and a lower electrode in an area in which the dedicated electrode wiring and the lower electrode overlap; a third insulating film and a fourth insulating film are stacked in an area which includes a forming area of the dedicated electrode wiring; in at least a portion of a forming area of the dedicated liquid chamber, there is provided a non-film forming area; and, in an area including a piezoelectric element forming section, either the first insulating film and the fourth insulating film are formed in the non-film forming area, or the fourth insulating film is formed in the non-film forming area.
