ABSTRACT:
The liquid discharge head has a three-dimensional structure which defines a space including a pressure chamber filled with liquid and a flow channel for supplying the liquid to the pressure chamber, the three-dimensional structure being formed by depositing a composition material on a substrate according to a deposition method, and a drive element which causes discharge of the liquid from the pressure chamber through a nozzle.
