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.
