摘要： A fuel injection valve has a valve body for opening and closing a valve seat, and receives an operation signal from a control unit to operate the valve body so that fuel is injected from a plurality of injection holes formed in an injection hole plate welded through a welded portion to a downstream side of the valve seat while passing through a gap between the valve body and the valve seat. The injection hole plate is formed at its central portion with a convex portion which is substantially axisymmetric with respect to a valve seat axis and which has a circular-arc shaped cross section, and the welded portion is also substantially axisymmetric with respect to the valve seat axis. Inlet portions of the injection holes are disposed in an injection hole arrangement surface diametrically outside of the convex portion and diametrically inside of a valve seat opening inner wall which is a minimum inside diameter of the valve seat, and the injection hole arrangement surface is coplanar with a surface having the welded portion.
