PROBLEM TO BE SOLVED: To provide a manufacturing method which enables a liquid ejection head for use in an electrostatic inkjet recording apparatus to be manufactured with high productivity. SOLUTION: Characteristically, this manufacturing method for the liquid ejection head comprises: a step of creating a locating mask, where prescribed areas forming a plurality of through-holes (e. g. ejection ports for ejecting a droplet by making an electrostatic force act on a solution with dispersed charged particles) are two-dimensionally arranged, on a substrate composed of at least one insulator layer and at least one metallic layer; and a step of forming the through-hole by making the hole penetrate each of the prescribed areas of the substrate through the use of a sandblasting method.
