Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injection valve creating a fuel liquid film which can be easily atomized. SOLUTION: A fuel impingement surface on which injected fuel from an injection hole impinges and the fuel liquid film is created is inclined to an axis of the injection hole, is a curved surface convex to a side on which the injected fuel impinges, and includes a flashing edge part at a downstream side of fuel. The fuel impingement surface is an outer circumference surface of a roughly cylindrical shape fuel impingement member having a diameter larger than the injection hole or an inner circumference surface of an opening surrounding the injection hole of a plate member, and is a developable surface such as a column surface, a cone surface, and a tangent surface. The fuel liquid film which can be easily atomized is stably created. COPYRIGHT: (C)2010,JPO&INPIT
