  • Patent number: 8171635
    Abstract: A method of manufacturing a liquid ejecting head is disclosed. The head includes first and second supply members forming parts of a liquid supply passage. The liquid ejecting head includes a filter disposed between the first and second supply members so as to cross the liquid supply passage, and an integrally molded member fixing the first and second supply members by a resin in a state where the filter is nipped between the first and second supply members. The method includes: disposing the filter in one of the first and second supply members; nipping the filter by the first and second supply members in a state where the filter is sucked, adsorbed, and positioned via a suction hole of the first or second supply member; and forming the integrally molded member in the state where the filter is nipped between the first and second supply members.
