Patent number: 8551351Abstract: A nozzle plate has a nozzle hole for ejecting liquid, which penetrates in a thickness direction of the nozzle plate. An ejection face of the nozzle plate having an ejection opening of the nozzle hole is covered with a water-repellent coat having a through hole communicating with the nozzle hole. The through hole has a straight portion and a diameter expansion portion. The straight portion is contiguous to the nozzle hole and having the same diameter as the ejection opening. The diameter expansion portion is provided to interpose the straight portion with the nozzle hole and gradually expanding so that a part thereof farther from the straight portion has a larger diameter than a part thereof closer to the straight portion.Type: GrantFiled: June 6, 2011Date of Patent: October 8, 2013Assignee: Brother Kogyo Kabushiki KaishaInventor: Hikaru Nakamoto
