摘要： A liquid ejection head includes an ejection element substrate, an electrical contact portion, a housing, and an opening/closing member. The ejection element substrate ejects liquid to perform recording. The electrical contact portion is electrically connected to an electrical wiring unit of an ejection apparatus to supply power to the ejection element substrate. The housing includes an opening portion into which the electrical wiring unit is inserted and to be provided with the electrical contact portion inside. The opening/closing member opens and closes the opening portion. In a closed state in which the opening/closing member closes the opening portion, the electrical wiring unit is sandwiched between the opening/closing member and a part of the housing.

摘要： Provided is a liquid ejection head and a liquid ejection apparatus in which separation of ejection modules from a support member is suppressed. To this end, a liquid supply unit is aligned with respect to the support member to which the ejection modules are bonded. Moreover, in a connection unit of an ejection unit and the liquid supply unit, liquid connection units of the ejection unit are connected to be movable relative to the liquid supply unit.

摘要： An object is to improve the structural reliability of a liquid ejection head. To achieve this, a liquid ejection head includes a first substrate having ejection ports, liquid chambers, and energy generation elements, and a second substrate joined to a second surface of the first substrate situated opposite to its first surface. The first substrate includes projecting areas projecting from end portions of the second substrate in a planar direction perpendicular to a first-axis direction (z-axis direction). Terminals to be electrically connected to the energy generation elements are provided at the second surfaces of the projecting areas. A support member 401 is joined to the first surface of the first substrate, has an opening at a position opposed to where the ejection ports are formed, and is fixed to the frame.

摘要： A technology capable of suppressing misalignment of the arrangement position of an ejection substrate even if a flow path member thermally expands is provided. A module equipped with a substrate that ejects a liquid and a flow path that is fluidly connected to the substrate is inserted and engaged with a frame that supports a support member for supporting the substrate so that the frame and the flow path face each other via a space in a direction intersecting an inserting direction. Further, the module abuts on the frame in the inserting direction in a case of being inserted and engaged with the frame, so as to be supported.
