DROPLET EJECTION HEAD AND METHOD FOR MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a droplet ejection head that reliably prevents an orifice plate from being deflected with a simple constitution and reduces an effect of the deflection of the plate even when the plate thickness is reduced and the gap between an energy generating element and the plat...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a droplet ejection head that reliably prevents an orifice plate from being deflected with a simple constitution and reduces an effect of the deflection of the plate even when the plate thickness is reduced and the gap between an energy generating element and the plate is reduced, and to provide a method for manufacturing the same.SOLUTION: The droplet ejection head is configured by laminating a substrate with an energy generating element applying energy to the liquid to eject the liquid droplet from an ejection orifice, on an orifice plate with the ejection orifice formed thereon, via a flow passage member having a pattern of a liquid flow passage. In the method for manufacturing the droplet ejection head, at least one of the plate and the flow passage member before lamination has at least one void of a through-hole and a recess other than the ejection orifice on the lamination surface of the plate and the flow passage member. The manufacturing method contains steps 1 to 5 defined in the specification.
