Inkjet head, filter plate for inkjet head, and method of manufacturing filter plate

摘要

An ink channel is formed in an inkjet head, so that ink introduced through an ink inlet passes through a pressure chamber and is ejected out of a nozzle. A filter for filtering the ink is disposed in the ink channel. The filter includes a depression formed in a plate, and a plurality of through-holes formed in the bottom of the depression. The filter has small channel resistance and is easy to handle.
