Abstract:
A liquid ejecting head comprising, a plurality of nozzle openings, a first flow passage, a circulation flow passage, a filter chamber, and a bypass flow passage, an inner diameter of the bypass flow passage is larger than a diameter of the hole of the filter, the inner diameter of the bypass flow passage is larger than a diameter of the nozzle opening, and a flow passage resistance of the bypass flow passage is larger than a flow passage resistance of the circulation flow passage from a branch point where the bypass flow passage branches from the supply passage to a junction point where the bypass flow passage merges into the collection passage.
