PROBLEM TO BE SOLVED: To provide an electromagnetic fuel injection valve in which ignitability of an ignition plug is excellent, fuel economy is improved and exhaust gas is reduced, by mutually colliding jets from injection holes 23 to atomize sprays 24 and forming various spray patterns of high flexibility such as a flat type spray and a hollow cone type spray. SOLUTION: By focusing attention on a point that the flat sprays 24 from a pair of the injection holes 23 form a spray unit 31 and a plurality of the spray units 31 are combined to form a spray group 32A in an optional shape, sprays of fuel from the pair of the injection holes 23 are mutually collided to form flat sprays 24 to form the spray unit 31 and a plurality of the pairs of the injection holes 23 capable of forming the spray units 31 are disposed. By combining a plurality of the spray units 31, the spray group 32A can be formed in the optional shape. COPYRIGHT: (C)2004,JPO
