According to one embodiment, an ink-jet head includes a substrate, a piezoelectric member, electrically conductive portions, a frame member, an insulating film, an electronic component and a protective agent. The piezoelectric member is mounted on the substrate and includes pressure chambers. The electrically conductive portions extend from the pressure chambers and are disposed on the substrate. The frame member inside which the piezoelectric member is disposed is attached to the substrate from above the electrically conductive portions. The insulating film covers the piezoelectric member, the frame member, and a part of the electrically conductive portions. The electronic component is connected to the electrically conductive portions. The protective agent covers an end portion of the insulating film located between the frame member and the electronic component and the electrically conductive portions between the electronic component and the end portion of the insulating film.
