Abstract: An object of the present invention is to provide a liquid ejection head which can achieve suppressing the influence of static electricity and the increase of a mounting force as well as downsizing and space saving of the liquid ejection head. The liquid ejection head is attachable and detachable with respect to a body connector provided on a liquid ejection apparatus body. Further, the liquid ejection head includes a head connector including a terminal which can be electrically connected to the body connector and a grounding member which is held at a coverage position where the terminal is covered in a non-contacting state with the body connector. The grounding member is formed with a deformable electroconductive member, and, as the head connector is made to move to a mounting position with respect to the body connector, is pressed by the body connector and is displaced to a position apart from the coverage position. Thus, the body connector can be connected with the terminal.

Abstract: A method of manufacturing a liquid ejecting method includes: a first step of injection molding passage members collectively constituting a passage for a liquid in the liquid ejecting head; a second step of moving the passage members to bring the passage members into contact with each other; and a third step of injecting a sealing material into a space between the passage members held in contact with each other, and filling the space with the sealing material. The sealing material is injected and filled, from a gate on a longitudinal side of the passage members, in a direction intersecting with a longitudinal direction of the passage members.

Abstract: A housing and a cover member are injection-molded and these housing and cover member are joined within a pair of mold. When the housing and the cover member are joined by molten resin, a mold for suppressing deformation is positioned at a face of the housing opposite to a face receiving a pressure of the molten resin.

Abstract: An opposed surface of a first flow path forming member has a groove portion forming a supply passage, and a protruding portion protruding from the edge of the groove portion to form the side wall of the groove portion. An opposed surface of a second flow path forming member has a lid portion that abuts against the protruding portion of the first flow path forming member to cover the opening of the groove portion in the first flow path forming member. A joining member is formed by injection-molding of a resin to abut against an outer surface of the protruding portion of the first flow path forming member and the opposed surfaces of the first and second flow path forming members.
