Fuel Injection Valve

An object of the present invention is to provide a fuel injection valve capable of suppressing fuel adhesion to a nozzle surface. Therefore, an injection hole has a curved surface portion E formed between a peripheral edge I of an inlet opening G and an inner peripheral surface F. The curved surface portion E has a center-side curved surface portion AE and an outer-peripheral-side curved surface portion BE. The center-side curved surface portion AE is formed to have a width WAE that is larger than the width WBE of the outer-peripheral-side curved surface portion BE.
