Abstract
A liquid ejection head manufacturing method comprising a step of forming a laminate, a step of connecting and a step of forming a protection film. The laminate includes electrodes and flow paths of liquid. The step of connecting is connecting terminals of a wiring substrate to terminals of the electrodes. The protection film is formed using atomic layer deposition, on a surface of the laminate defining the flow paths after connecting the terminals.
