In an inkjet head acting as a liquid ejecting head for carrying out a print operation by ejecting liquids onto a medium to be recorded, the inkjet head including two rows of orifice arrays, which are disposed approximately parallel with each other and a group of supply ports for feeding the liquids to the orifice arrays, the orifice arrays and the supply ports being arranged integrally, and only one of the two rows of the orifice arrays being used, a dummy heater board having the same shape as that of a heater board is caused to come into intimate contact with an unused side liquid chamber. Further, ribs are disposed in the vicinity of an unused side ink path so as to increase strength. With this arrangements, an intimate contact property can improved, irregular print can be eliminated and the disposition of orifice arrays on a top plate as a single isolated member can be reproduced even at the time the inkjet head is completed.
