Abstract: A liquid ejection head can suppress the influence of static electricity and the increase of a mounting force as well as downsize and save space 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.
