Claims
- 1. An ink jet head comprising:a nozzle plate having a nozzle hole and a film having at least one of a water repellent function and an oil repellent function formed on one plate face thereof, wherein said film comprises a mixture of a metal oxide and fluorine based resin, and a percentage of the metal oxide of a mixture ratio of the mixture gradually decreases in a direction distant from a plate face of a nozzle plate in a thickness direction of said film.
- 2. An ink jet head comprising:a nozzle plate having a nozzle hole and a film having at least one of a water repellent function and an oil repellent function formed on one plate face thereof, wherein said film comprises a mixture layer having a metal oxide and fluorine based resin mixed with each other.
- 3. An ink jet head comprising:a nozzle plate having a nozzle hole and a film having at least one of a water repellent function and an oil repellent function formed on one plate face thereof, wherein said film is formed by sequentially continuously providing a metal oxide layer, a mixture layer having a metal oxide and fluorine based resin mixed with each other therein, and a fluorine based resin layer on a plate face of said nozzle plate by chemical vapor deposition.
- 4. An ink jet head comprising:a nozzle plate having a nozzle hole and a film having at least one of a water repellent function and an oil repellent function partly formed on one plate face thereof, wherein the film comprises a metal oxide layer, a fluorine layer, and a mixture layer having a metal oxide and fluorine based resin mixed with each other.
- 5. The ink jet head according to claim 4, wherein the mixture layer is interposed between the metal oxide layer and the fluorine based resin layer.
