Abstract:
An ejection energy generating element is provided in a first pressure chamber so that a liquid in the first pressure chamber is ejected from an ejection port. A pressurization energy generating element is provided in a second pressure chamber so that the liquid in the first pressure chamber is pressurized. An opening area of a hole open to the second pressure chamber is smaller than an opening area of the ejection port.
