Abstract:
Provided is a liquid ejection head substrate, in which a plurality of units are arranged. Each of the units includes: a pressure generating element formed on a first surface of a support substrate; and a pair of independent liquid chambers, which are formed on both sides of the pressure generating element so as to be opposed to each other, and are opened to the first surface of the support substrate. The liquid ejection head substrate includes, in the support substrate: a first common liquid chamber communicating to a plurality of independent liquid chambers on one side of the pair of independent liquid chambers; a second common liquid chamber communicating to a plurality of independent liquid chambers on another side of the pair of independent liquid chambers; and a partition wall separating the first common liquid chamber and the second common liquid chamber from each other.

Claim (Index 9):
A liquid ejection head, comprising:\n the liquid ejection head substrate of  claim 1 ; and a member, which is formed on the first surface of the support substrate, and includes:\n one pressure generating chamber communicating to the pair of independent liquid chambers for each of the plurality of units; and \n an ejection orifice communicating to the one pressure generating chamber, \n wherein the liquid ejection head is capable of circulating liquid in the one pressure generating chamber from one of the first common liquid chamber and the second common liquid chamber to another of the first liquid chamber and the second liquid chamber through the pair of independent liquid chambers.
