摘要： An ink jet head has a first member having a plurality of energy generating elements for generating energy necessary for ejecting ink, a second member having a plurality of grooves separated by land portions, the grooves constituting an array of ink channels leading to an array of ink ejecting openings and the land portions constituting ink channel walls separating the ink channels, and a pressing member for pressing the first member and the second member to each other, thereby joining these members so that the ink channels are formed by cooperation between the first member and grooves in said second member. The height of ink channel walls is varied such that it is smaller at both end regions of the array of ink channels than at the central regions of the array of ink channels. Close and tight contact between the first member and the second member is attained in the central region of the ink channel array where the ink channels actually perform ejection of ink, so that ink can be discharged accurately without any crosstalk between adjacent ink channels, thus ensuring high quality printing.
