This abstract first appeared for US patent application 18894383 titled 'LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS
Original Abstract Submitted
An object is to provide a liquid ejection head that can be mounted on a liquid ejection apparatus easily. The liquid ejection head comprises: a storing unit configured to store liquid; an element substrate having an ejection port surface in which an ejection port for ejecting liquid stored in the storing unit is formed; and an electrical circuit substrate electrically relaying a liquid ejection apparatus and the element substrate. In a posture in which the liquid ejection head is mounted on the liquid ejection apparatus, the electrical circuit substrate is located above the element substrate in the vertical direction, on the electrical circuit substrate, a connector for electrically connecting with an electrical connecting member comprised by the liquid ejection apparatus is provided, and on the electrical circuit substrate, the connector is provided only on a top surface facing in a direction opposite to the ejection port surface.
