PROBLEM TO BE SOLVED: To provide a fuel injection valve having a simple configuration by use of bellows. SOLUTION: In this fuel injection valve 1, an energizing means for energizing a valve element 9 in the direction of valve closing is used as expansible bellows 12 for generating elastic force. It is possible to dispense with an adjuster capable of fitting and inserting (press-fitting) the bellows 12 itself into a core cylinder 5 easily and securely and used to fix a coil spring as an energizing means and adjust energizing force conventionally.
