Abstract
A fuel injection valve includes: a swirl chamber having an inner peripheral wall formed to be gradually increased in curvature toward a downstream side from an upstream side; a swirl passage, through which a fuel is introduced into the swirl chamber; and a fuel injection port opened to the swirl chamber, wherein the swirl chamber and the swirl passage are formed so that a side wall of the swirl passage connected to a downstream end side of the swirl chamber, or an extension thereof is made not to intersect a downstream side portion of the inner peripheral wall of the swirl chamber, or an extension thereof.
