摘要： A liquid-jet head capable of preventing malfunction attributable to an external environment such as humidity of a piezoelectric element and of achieving miniaturization thereof, a manufacturing method thereof and a liquid-jet apparatus are disclosed. The liquid-jet head including a passage-forming substrate in which a pressure generating chamber communicating with a nozzle orifice ejecting a liquid is defined and a piezoelectric element composed of a lower electrode, a piezoelectric layer and an upper electrode on one surface of the passage-forming substrate with a vibration plate interposed therebetween, wherein the liquid-jet head includes a sealing plate joined to a piezoelectric element aide of the passage-forming substrate and having a piezoelectric element holding portion, the sealing plate hermetically sealing a space secured in a region facing to the piezoelectric element to an extent not to hinder a movement thereof, and at least a part of a peripheral portion of the piezoelectric element holding portion of the sealing plate is joined to the passage-forming substrate via a glass joining layer made of glass. Thus, intrusion of moisture into the piezoelectric element holding portion is prevented.

摘要： Disclosed are an ink-jet recording head capable of preventing destruction of a piezoelectric element relatively readily and securely and an ink-jet recording apparatus. In the ink-jet recording head including a passage-forming substrate having a pressure generating chamber communicating with a nozzle orifice defined therein and a piezoelectric element provided on a region of the passage-forming substrate via a vibration plate, the region corresponding to the pressure generating chamber, a sealing member defining a piezoelectric element holding portion securing a space not to hinder a movement of the piezoelectric element is provided, the sealing member being joined onto a side of the piezoelectric element of the passage-forming substrate, and at least one sealed portion as a space provided in a member other than the sealing member, communicating with the piezoelectric element holding portion and shielded from outside air is provided, thus volume of the piezoelectric element holding portion is substantially expanded to prevent an increase in humidity of the piezoelectric element.
