PROBLEM TO BE SOLVED: To provide a nozzle plate for a liquid ejector head and a liquid ejector head each of which is provided with filling property, ejection stability and reliability, and a liquid ejector, a liquid ejection method, and an inkjet recording apparatus and an inkjet recording method. SOLUTION: The nozzle plate for the liquid ejector head includes a nozzle hole for ejecting droplets composed of an ejection liquid, wherein the surface energy of the inner wall of the nozzle hole at 25 is lower than the surface tension of the ejection liquid at 25°C , and the surface energy of the inner wall of the nozzle hole at 25°C is the same as the surface energy of the ejection side surface of the nozzle plate at 25°C. A mode in which a difference (B-A) between the surface energy (A) of the inner wall of the nozzle hole at 25°C and the surface tension (B) of the ejection liquid at 25°C is higher than 0 mN/m and equal to or lower than 10 mN/m, and a mode in which the surface energy of the inner wall of the nozzle hole at 25°C is equal to or lower than 25mN/m or the like are preferable.
