ABSTRACT:
An inkjet head capable of achieving stable ejection of ink by preventing air bubbles from being left in the upstream side of a nozzle of a filter element such as mesh filter that is provided in an inkjet head owing to the efficient use of the open area of the filter element. The inkjet head is provided to have a fluid channel communicated with the atmosphere from the upstream side region of the filter element such as mesh filter, with regard to the nozzle without passing through the filter element and the nozzle.
