A fuel injection valve has a first and a second injection ports whose central axes are parallel to each other, the central axis of the second injection port is out of alignment with respect to the central axis of the first injection port so that, when the largest length M1 of a longer-side line along which a plane including the central axis of the valve seat member and the central axis of the second injection port intersects with an inner wall of the second injection port is larger than the shortest length M2 of a shorter-side line along which the above plane intersects with an inner wall of the second injection port, the distance W1 from the inner wall of the first injection port to the longer-side line of the second injection port as measured within the plane is larger than the distance W2 from the inner wall of the first injection port to the shorter-side line of the second injection port as measured within the plane.
