PROBLEM TO BE SOLVED: To provide a liquid ejector with improved performance for ejecting oil or liquid completely. SOLUTION: An ejection rim 36 of the liquid ejector comprises a flow path face 38, a rear path face 40 placed on its rear, and a rim end face 42 connected between a tip of the flow path face 38 and a tip of the rear path face 40, wherein an angle β of a tangential line at the tip of the rear path face 40 is selected, thereby allowing liquid to flow down from the rim end face 42 without reaching the rear path face 40 on the ejection rim 36. Since the rim end face 42 is a horizontal flat face and free from sharp edges, manufacture by injection molding is facilitated. |
