发明名称 Liquid ejection head, liquid ejection apparatus, and manufacturing method of liquid ejection head
摘要 A liquid ejection head includes an energy-generating element arranged on a semiconductor substrate, a barrier layer deposited on the semiconductor substrate for forming a liquid chamber in the periphery of the energy-generating element, and a nozzle sheet bonded on the barrier layer and having a nozzle formed at a position opposing the energy-generating element, in which the liquid ejection head ejects liquid contained in the liquid chamber from the nozzle as liquid droplets by the energy-generating element, and the barrier layer is provided with a plurality of depressions, each having an independent contour, arranged within a range, which is separated from the border of the barrier layer, on an adhesive region adhering to the nozzle sheet.
