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 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. The passage 21a for swirl is provided in an inclined manner on the side of the fuel injection hole 23a positioned on the downstream side of the swirl chamber 22a. |
