Abstract
In an inkjet recording head comprising a substrate including an energy-generating element that generates energy for ejecting a liquid, an ejection port for ejecting the liquid, and a liquid flow passage communicating with the ejection port, a liquid-repellent layer is formed on a surface of a member for forming the ejection port, and a liquid-repellent region and a liquid-nonrepellent region are formed on the same surface of the liquid-repellent layer by irradiating a part of the liquid-repellent layer with light including a wavelength decomposing the liquid-repellent component in the liquid-repellent layer.
