Summary:PROBLEM TO BE SOLVED: To provide a fuel injection valve that improves uniformity in a circumferential direction of a swirl flow.SOLUTION: A fuel injection valve includes: a swirl chamber 22a that has an inner peripheral wall formed so that curvature can be gradually increased toward a downstream side from an upstream side; a passage 21a for swirl, which has an inflow area 20b in a valve stem direction and which introduces fuel into the swirl chamber 22a; and a fuel injection hole 23a that is opened in the swirl chamber 22a. Connection is performed in a central part of an orifice plate, and the height of the passage 21a for swirl is set smaller toward a connection part 25.
