PROBLEM TO BE SOLVED: To form a spray which can exert good performance in both uniform combustion and stratified charge combustion, in a fuel injection valve. SOLUTION: The fuel injection valve has a injection hole group 230 of a plurality of injection holes for injecting fuel. Upstream of the injection hole group, a valve seat, a valve element opening/closing a clearance between the valve element and the valve seat to open/close a fuel passage, and a drive means driving the valve element are provided. The injection hole group 230 has a plurality of injection holes 211 to 216 perforated to be different in angles of directions of axes of the holes, and a plurality of injection hole pairs made by combining these injection holes. The plurality of injection hole pairs have a first combination 230a in which an angle between the axes of the injection holes is large, and a second combination 230b in which an angle between the axes of the injection holes is smaller than that of the first combination 230a.
