Abstract:
1. A method of manufacturing a printer head which changes the volume of an ink liquid cell by moving a movable electrode to eject an ink droplet from a predetermined nozzle, the movable electrode being moved by electrostatic force generated between a fixed electrode and the movable electrode, the method comprising: a fixed-electrode formation step for forming the fixed electrode on a predetermined substrate; a sacrificial-layer formation step for forming a sacrificial layer on the fixed electrode; a movable-electrode formation step for forming the movable electrode on the sacrificial layer; a sacrificial-layer removal step for removing the sacrificial layer to form a space between the fixed electrode and the movable electrode; a mold formation step for forming a mold on the top surface of the movable electrode, the mold corresponding to at least a space for the ink liquid cell and a space for an ink channel that introduces ink to the ink liquid cell; a deposition step for depositing a coating material that forms partitions of the ink liquid cell and the ink channel and a coating material that forms a partition of a nozzle to cover the mold; and a mold-removal step for removing the mold after the formation of the partitions using the coating material.
