LIQUID DROP EJECTION HEAD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that wiping resistance and nozzle port accuracy are not compatible. SOLUTION: A nozzle plate 43 is formed by laminating an organic resin member 71 and a high rigidity member 72, and laminating a fine particulate layer 74 containing fine particulate 82 of an organic material and a water repellent layer 75 on a surface of the organic resin member 71 sequentially.
