An ink jet recording head and a manufacturing method thereof enables no ink electrolysis to be generated, such occurrence of the ink electrolysis is caused by construction or mechanism of respective ink jet recording head using piezoelectric body. Ink channel and dummy channel are formed alternately at the both sides of a side wall of piezoelectric body respectively. There is discharged ink drop while changing volume within the ink channel by applying electric field using electrode formed within respective channels. An electrode formed on respective ink channels is taken as common electrode, while electrodes formed on respective dummy channel are taken as individual electrodes, thus causing no ink to be contacted with a passivation film formed on the individual electrodes.
