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 20):
A liquid ejection head, comprising:\n a plurality of nozzles; and a supply passage through which a liquid is supplied to the nozzles, wherein the supply passage includes\n a first flow passage, and \n a second flow passage connected to the first flow passage and including two sections that extend in mutually 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, \n wherein the second flow passage has a liquid flow resistance larger in a first section as one of the two sections than in a second section as the other of the two sections, 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, wherein the liquid ejection head comprises a plurality of first flow passages, each as the first flow passage, which are disposed so as to be shifted from one another in the second direction; and a plurality of second flow passages, each as the second flow passage, which are arranged in a third direction orthogonal to both of the first direction and the second direction, the second flow passages being connected respectively to the first flow passages, and wherein the second flow passages have respective protrusions, each as the protrusion, which have mutually different shapes.
