The chamber formation plate is comprised of nickel. A sealing plate is joined to the first face of the chamber formation plate so as to seal the recesses to form a plurality of pressure generating chambers. A metallic nozzle plate is formed with a plurality of nozzles, and joined to the second face of the chamber formation plate such that each of the nozzles is communicated with associated one of the pressure generating chamber via the through hole. A ratio of a grain size of a crystal of the nickel with respect to a thickness of a partition wall defined between each adjacent ones of the recesses is 60% or less.

摘要： There is provided a first die, in which a plurality of projections are arrayed in a first direction with a fixed pitch to form at least one array of the projections. Each of the projections is elongated in a second direction perpendicular to the first direction. The first die faces a first face of the plate member. A second die is opposed to the first die while supporting a second face of the plate member. At least one first region is formed on the plate member so as to have a less rigidity than another region of the plate member. The first die and the second die are approached so that the projections are dug into a second region in the first face of the plate member, thereby forming partitioned recesses to be pressure generating chambers of a liquid ejection head. The at least one first region is adjacent to at least one of ends in the first direction of the second region, such that the first region and the second region are arranged in the second direction.

摘要： There is provided a first die in which a plurality of projections are arrayed in a first direction with a fixed pitch. Each projection is elongated in a second direction perpendicular to the first direction. The first die faces a first face of a plate member. A second die is opposed to the first die while supporting a second face of the plate member. At least one dam member is provided in at least one of the first die and the second die, so as to project from one of the first die and the second die toward the other. The first and second dies are approached so that the dam member is dug into at least one of the first face and the second face. The first and second dies are further approached so that the projections are dug into a first region in the first face, thereby forming partitioned recesses to be pressure generating chambers of a liquid ejection head. The dam member is situated in the vicinity of at least one of ends in the first direction of the first region, thereby suppressing a plastic flow of the material in the first direction caused by the dug projections.
