An ink jet recording head has a plurality of ink channels (1bc, 1de), disposed on a piezoelectric substrate (11), for receiving liquid ink therein, a plurality of dummy channels (2ab, 2cd) arranged alternately with the ink channels (1bc, 1de) on the substrate (11), a top plate (4) for covering the ink channels (1bc, 1de) and dummy channels (2ab, 2cd), and a nozzle plate (5) defining the front end of the channels and having a nozzle (6fg, 6hi) for each of the ink channels (1bc, 1de) for ink ejection. The dummy channels (2ab, 2cd) have a depth larger than the depth the ink channel (1bc, 1de), and the top plate (4) has a slit (13) extending along each of the dummy channels (2ab, 2cd), for reducing cross-talks between adjacent ink channels (1bc, 1de). <IMAGE> |
