A method of manufacturing a flow path member includes inserting the first flow path member into each concave portion of the second flow path member and welding the first flow path member and the second flow path member in a circumferential direction of a region where the first flow path and the second flow path communicates each other; and providing two or more injecting portions which are provided with a gap wider than a gap between a wall surface of the concave portion which faces the first flow path member and a circumference surface of the first flow path member inserted into each concave portion which faces the wall surface, communicate with each concave portion, and are opened to the same side as the concave portion to have a concave shape to each concave portion in the second flow path member.

A liquid ejection head includes a head main body which discharges liquid, a flow path member main body on which a liquid reception member for receiving liquid supplied from the outside is formed, a first case, a second case, and a first insertion portion which is provided on the flow path member main body and through which a securing member for securing the first case, the second case, and the flow path member main body to one another is inserted. In the liquid ejection head, the first insertion portion is formed such that the outer wall covers an exposing portion from which the securing member is exposed.

A liquid ejecting head includes: a head main body including a nozzle opening that ejects a liquid; and a fixed plate fixed to a liquid ejecting surface of the head main body, and including an exposure opening, the nozzle opening of the head main body being formed in the liquid ejecting surface of the head main body, the nozzle opening of the liquid ejecting surface being exposed to the exposure opening. A positioning hole open to the liquid ejecting surface and positioned with respect to the nozzle opening is provided in the head main body. The fixed plate is fixed to the liquid ejecting surface so as to close the positioning hole. The fixed plate includes an extension portion protruding from the liquid ejecting surface. At least two head positioning holes are provided in the extension portion.

A head module includes a head unit having a plurality of heads, a carriage to which the head unit is anchored and that moves in a first direction relative to a recording sheet, and a grounding member that electrically connects the heads to the carriage; the heads are each provided with a cover head that covers first side surfaces and second side surfaces of the heads. Plate-shaped contact portions of the grounding member are caused to make contact with side wall portions of the cover head that are parallel to the first direction.

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.
