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 107 has a curved surface portion 107E formed between a peripheral edge 1071 of an inlet opening 107G and an inner peripheral surface 107F. The curved surface portion 107E has a center-side curved surface portion 107AE and an outer-peripheral-side curved surface portion 107BE. The center-side curved surface portion 107AE is formed to have a width W107AE that is larger than the width W107BE of the outer-peripheral-side curved surface portion 107BE.
