Abstract
A method for manufacturing an inkjet head having a pressure chamber that stores ink, a nozzle that is provided at the pressure chamber and ejects the ink, and an actuator that changes an internal pressure of the pressure chamber to eject the ink in the pressure chamber through the nozzle. The method includes the steps of: forming the actuator on a substrate by using one of a liquid phase method and a vapor phase method to manufacture an upper structure; separating the upper structure from the substrate; forming a lower structure having the pressure chamber with metallic glass, independently of the substrate; and joining the upper structure and the lower structure.
