ABSTRACT:
There is disclosed a method of producing an inkjet printhead including a cavity unit having therein ink passages and formed by stacking a plurality of kinds of flat plates each of which has a specific ink-passage pattern for constituting the ink passages. The method comprises: preparing a large-sized material sheet for each kind of a plate, such that the material sheet comprises a plurality of plate regions, each of which corresponds to one individual plate of the kind, and which are contiguous to one another such that a reserved region for cutting is between each adjacent two plate regions and there is left no margin at a periphery of the material sheet; obtaining a laminate of the material sheets by stacking the material sheets of respective kinds of plates, with the corresponding plates in the respective material sheets aligned in a direction of stacking of the material sheets; and obtaining a plurality of individual laminates by cutting the laminate of the material sheets at the reserved region into the individual laminates.
