<p>Disclosed is an ink jet head exhibiting good assemblability while protecting an electrode portion. An ink jet head (10) comprising a head chip (2) including drive walls (22) and channels (23) juxtaposed alternately with a drive electrode (25) being formed on the drive wall (22), and a nozzle plate (24) wherein a connection electrode is formed on the rear surface of the head chip (2), a wiring board (3) on which an electrode portion (32) is formed is bonded to project from the head chip (2), and ink in the channel (23) is ejected by causing shear deformation of the drive wall (22) is further provided with a holding member (5) disposed at a position covering the electrode portion (32) and holding a portion (31) of the wiring board (3) projecting from the head chip (2), and an electrode portion protection member (4) bonded between the holding member (5) and the electrode portion (32) using adhesive and having a thickness in the range of 0.01-0.5 mm at a part covering the electrode portion (32).</p> |
