<p>It is described an ink jet print head that has a flow path forming member (3) having pressure generating chambers (4), ink supply paths (5), and reservoirs (6), a nozzle plate (2) for covering one side of the flow path forming member (3), the nozzle plate (2) having nozzle openings (1) continuous to the pressure generating chambers (4), a flexible wall member (10) for varying the volumes of the pressure generating chambers (4), the flexible wall member (10) covering the other side of the flow path forming member (3), and piezoelectric vibrating elements (7) for elastically deforming the flexible wall member (10), the piezoelectric vibrating element (7) being in contact with the flexible wall member (10). The ink jet print head is improved in that the flexible wall member (10) includes low elasticity portions (11) and high elasticity portions (12) for transmitting expanding and compressing motions of the piezoelectric vibrating elements (7) to the pressure generating chambers (4), one end (12b) of each high elasticity portion (12) being extended to a region of the ink supply path (5). <IMAGE></p> |
