Abstract
When injection-hole inlets and injection-hole outlets are projected vertically onto an X-Y plane (N) perpendicular to a valve-seat axial center, an injection-hole arrangement angle (θ), which is formed by a straight line (a) passing through a center of the injection-hole inlet of a reference injection hole and the valve-seat axial center and a straight line (b) passing through a center of the injection-hole inlet of the injection hole neighboring the reference injection hole and the valve-seat axial center on the plane (N), is set so as to become smaller as being closer to a Y-axis. A fuel turn angle (α) on a wide-angle side, which is formed by the straight line (a) and a straight line (c) passing through a center of the injection-hole inlet and a center of the injection-hole outlet on the plane (N), has a relationship: 90°<α<180°.
