Abstract
An ink jet recording head has a plurality of ink channels, disposed on a piezoelectric substrate, for receiving liquid ink therein, a plurality of dummy channels arranged alternately with the ink channels on the substrate, a top plate for covering the ink channels and dummy channels, and a nozzle plate defining the front end of the channels and having a nozzle for each of the ink channels for ink ejection. The dummy channels have a depth larger than the depth the ink channel, and the top plate has a slit extending along each of the dummy channels, for reducing cross-talks between adjacent ink channels.
