Abstract
In order to avoid arty positional misalignment between an ink passage hole formed on a manifold plate and a nozzle formed on a nozzle plate, the nozzle plate on which no nozzle has been formed, is stacked on and bonded to the manifold plate having the ink passage hole. After the nozzle plate is bonded to the manifold plate, the nozzle is formed on the nozzle plate. Then, a water-repellent film is formed on an ink-discharging surface of the nozzle plate. Further, a cavity plate or the like is bonded to the manifold plate and an ink jet head is completed.
Claims10
A method of manufacturing an inkjet head, comprising:
- a step of bonding a surface of a first plate having an ink passage hole penetrating the first plate to a surface of a second plate;
- and
- a step of forming a throughhole penetrating the second plate, that is performed subsequent to bonding the first plate and the second plate, wherein the throughhole is communicated with the ink passage hole at a contact face between the first plate and the second plate and opens at an ink-discharging surface that is opposite the contact face.
