PROBLEM TO BE SOLVED: To sustain good adhesion between a liquid ejecting part and an ejection forming substrate by insert forming a member for urging a liquid ejection opening forming member toward the coupling member side at the time of machining the liquid ejection opening forming member and forming the liquid ejection opening forming member and the urging member integrally. SOLUTION: A base part 50 is secured to the outer circumferential surface at the bottom of an ink tank holder 46 and resin molded integrally with ink ejecting parts 52A, 52B. Each common liquid chamber and each ink channel of the ink ejecting parts 52A, 52B are brought into tight contact with the ink ejecting parts 52A, 52B thus forming a heater board. The heater board is connected electrically with printed wiring boards 54A, 54B and coupled with the ink ejecting parts 52A, 52B through leaf spring members 56A, 56B thus forming a leaf spring member 60, i.e., an urging member, being press fitted in a recess 58 between the ink ejecting parts 52A, 52B.
