PROBLEM TO BE SOLVED: To provide a technology capable of preventing variations in ink ejection amounts between nozzle holes and misfiring of the ink, and stably ejecting the ink in a printing apparatus having an electrostatic ejection type inkjet head.SOLUTION: A multi-nozzle plate includes first and second nozzle holes 1, 2 that penetrate a substrate. The multi-nozzle plate is used for an electrostatic ejection type inkjet head, in which first and second electrode layers 61, 62 are provided on inner wall surfaces 1a, 2a of the first and second nozzle holes 1, 2. Ink ejection ports 21, 22 of the first and second nozzle holes 1, 2 are provided at top parts of protruding first and second nozzle parts 31, 32 provided at the ink ejection side of the substrate 10. |
