The first and second metals can be independently selected from the group of titanium, vanadium, chromium, iron, cobalt, nickel, zirconium, niobium, molybdenum, ruthenium, rhodium, palladium, hafnium, tantalum, tungsten, osmium, iridium, or platinum, wherein the first metal and the second metal can be different metals. The dopant can be selected from the group of oxygen, nitrogen, or combinations thereof. The metalloid, first metal, second metal, and dopant can account for at least 70 at % of the amorphous thin metal film.

摘要： A liquid ejection head substrate has heating unit and an element array in which a plurality of ejection energy generating elements generating ejection energy for liquid ejection are arranged on a surface side of a base material. The heating unit includes a heating element extending in a direction of the element array and generating heat by being energized, wiring spaced apart from the heating element in a direction orthogonal to the surface of the base material, and a plurality of connecting portions connecting the heating element and the wiring to each other. The heating element, the wiring, and the plurality of connecting portions are provided in a region overlapping a region where the element array is disposed in a direction orthogonal to the direction of the element array when seen from the direction orthogonal to the surface of the base material. A current flows to the wiring in a middle of a path of the current flowing through the heating element when the heating element is energized.

摘要： A liquid containing member that can supply a liquid having a uniform concentration of a precipitating component to a liquid ejecting portion is provided. A liquid containing member includes: a liquid containing portion that can contain ink; a liquid supply port for supplying the ink contained in the liquid containing portion to a liquid ejection head; and a communication channel that is in communication with the liquid containing portion and the liquid supply port. The communication channel has a first end that is positioned at a lower end on the gravity direction side in the liquid containing portion and can suck the ink, and a second end that is positioned closer to the anti-gravity direction side than the first end is, and can suck the ink, in an in-use state in which the ink is supplied from the liquid supply port to the liquid ejection head.
