PROBLEM TO BE SOLVED: To improve atomization in an injection hole type fuel injection type fuel injection valve by effectively suppressing spray interference. SOLUTION: The fuel injection valve comprises: a nozzle body 16 in which a fuel passage is opened/closed by separation/contact of a valve element 15; and an injection hole plate having an injection hole injecting fuel flowing down the fuel passage in a form of spray. In the fuel injection valve, center side injection holes 42, 43 are formed to be close to the center of the plate, and outer peripheral side injection holes 44, 45 are formed to be close to an outer periphery of the plate.
