Abstract:
A liquid ejection head, including: nozzles; and a supply passage through which a liquid is supplied to the nozzles, wherein the supply passage includes (a) a first flow passage and (b) a second flow passage connected to the first flow passage and including two sections that extend in different directions from a connected position at which the first flow passage is connected to the second flow passage, the liquid being supplied to the second flow passage from the first flow passage, wherein the second flow passage has a liquid flow resistance larger in a first section than in a second section, and wherein a protrusion protruding toward the first flow passage is provided on an inner wall surface of the second flow passage facing the first flow passage, for permitting the liquid to more easily flow from the first flow passage into the first section than the second section.

Claim (Index 9):
The liquid ejection head according to  claim 8 ,\n wherein the tip of the protrusion is disposed at a position in the second direction at which a ratio of a distance between a portion of the first flow passage located on one of opposite sides of the tip of the protrusion on which the first section is located and a portion of the first flow passage located on the other of the opposite sides of the tip of the protrusion on which the second section is located is substantially the same as a ratio of the liquid flow resistance between the first section and the second section.
