摘要： A manufacturing method produces a liquid ejecting head including first and second flow path members having liquid flow paths that communicate with each other. An integrally-molded member is surrounds the second flow path member on the second flow path member side of the first flow path member to join the first and second flow path members together. A holding process defines a space portion for forming the integrally-molded member in a frame section. The frame section is brought into contact with a contact surface of a recessed portion in the face of the second flow path member opposite the first flow path member, with the first and second flow path members contacting each other such that the liquid flow paths communicate with each other. A molding process fills the space portion with resin, thereby molding the integrally-molded member, and joins the first and second flow path members together.

摘要： A method of manufacturing a liquid ejecting head that ejects a liquid supplied from a liquid storing member through a liquid supply path. The method includes positioning a filter to a first or second supply member by using positioning pins upon disposing the filter between first and second liquid supply paths. The first supply member has the first liquid supply path. The second supply member has the second liquid supply path on the side of one surface of the first supply member to communicate with the first liquid supply path. At least the first supply member and the second supply member are integrated such that a fixed portion is molded by injecting a resin material from an injection portion of a mold at a position where the first and second liquid supply paths are interposed between the positioning pins.
