Zusammenfassung:In a fuel injection valve having a pressure control chamber (11), a nozzle (50), and an electromagnetic valve (5), a fuel flow-in passage, a fuel flow-out passage and at least a part of the pressure control chamber are formed in a single piece of a plate (4) in such a manner that the part of the pressure control chamber is opened to an axial end surface of the plate and the fuel flow-out passage extends so as to penetrate the plate axially from an inner wall of the part of the pressure control chamber to another axial end surface of the plate and the fuel flow-in passage comprises a first passage (19) extending from the axial end surface of the plate and a second passage (17) extending from the inner wall of the part of the pressure control chamber, which intersect with each other within the plate, wherein an entrance orifice (18) is formed in first passage.
