    • PROBLEM TO BE SOLVED: To efficiently form a filter for suppressing clogging with ink in a manufacturing process of a head.
      SOLUTION: In the inkjet head 1, for constituting both an ink feeding passage 201 and a filter part 2f set on the ink feeding passage 201, first, a first and a second lamination plates 31b and 31a with a predetermined shaped part 32a and a non-shaped part 32b in the profile are formed. Moreover, the first and second lamination plates 31b and 31a are alternately combined and joined each other. Thus an inkjet head manifold 2 of a form with the ink feeding passage 201 and the filter part 2f arranged on the passage can be constructed. The passage of ink and the filter part 2f can be formed simultaneously, so that the productivity of the inkjet head 1 can be improved.
