Abstract
A liquid recording head includes a thermal energy generating element, having a flat plate configuration, for generating a bubble by thermal energy; a pressure chamber in which the thermal energy generating element is provided; a flow path for introducing liquid into the pressure chamber; a supply port in fluid communication with the flow path; and an ejection outlet provided at a position opposing the thermal energy generating element in fluid communication with the pressure chamber. The thermal energy generating element includes a first major surface facing the ejection outlet and a second major surface opposite the first major surface, and a distance between the first major surface and a ceiling surface of the pressure chamber in which the ejection outlet is formed is shorter than a distance between the second major surface and a bottom surface of the pressure chamber.
