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.

Claim (Index 1):
A liquid ejection head comprising:\n a first pressure chamber and a second pressure chamber, one end portion of the first pressure chamber being connected to a liquid supply path through a first flow path, one end portion of the second pressure chamber being connected to the liquid supply path through a second flow path, the other end portion of the first pressure chamber and the other end portion of the second pressure chamber being communicated with each other by a communication path; an ejection port open to the first pressure chamber; a hole open to the second pressure chamber; an ejection energy generating element provided in the first pressure chamber so that a liquid in the first pressure chamber is ejected from the ejection port; and a pressurization energy generating element provided in the second pressure chamber so that the liquid in the first pressure chamber is pressurized, wherein an opening area of the hole is smaller than an opening area of the ejection port.
