PROBLEM TO BE SOLVED: To provide a liquid-jet recording head and a manufacturing method whereby the generation of satellite liquid drops is suppressed and a printing quality is improved. SOLUTION: A resin molding 10A of a top plate constituting the liquid-jet recording head is uniformly and accurately formed by cutting a liquid channel groove form face 13 and a reference butt face 14 by a cutter 1, cutting a discharge opening surface 15 of an orifice plate 12 by a cutter 2 and removing a deflection of the orifice plate 12 resulting from resin molding. At this time of cutting, the discharge opening surface 15 is formed by an inclined cutting face of the cutter 2 to be inclined by an angleαequal to an angle of incidenceαof a laser light L for processing a discharge opening 17 later. The discharge opening surface 15 is formed perpendicularly to a liquid discharge axis direction of the discharge opening 17. Since an angular difference is not generated to an edge of the discharge opening, main drops of liquid drops discharged from the discharge opening and satellite drops are let to fly in the same direction, thereby improving the printing quality.
