Patent ID: 8608301

Claim:
A liquid ejecting head comprising: a head body including a nozzle opening; a filter having a predetermined area; an upstream passage that is arranged on an upstream side of the filter and is fluidly communicated with a face of the filter; a downstream passage to which the liquid that does not pass through the filter is flowed; a filter-downstream passage to which the liquid that has passed through the face of the filter is flowed and from which the liquid is led out to the head body; and an intermediate passage that is arranged between the upstream passage and the downstream passage, the face of the filter forming a side wall of the intermediate passage so that the fluid flowing through the intermediate passage from the upstream passage to the downstream passage flows over the face of the filter so as to inhibit the accumulation of bubbles on the face of the filter, the filter separating the intermediate passage from the filter-downstream passage, wherein a thickness of the intermediate passage in a direction opposing the face of the filter is smaller than a thickness of the upstream passage and the downstream passage in the same direction as the direction of the thickness of the intermediate passage.
