Zusammenfassung:An objection of the present invention is to provide a fuel injection valve with a reduced variation in an injection amount and, in order to achieve this object, a method for adjusting stroke, the method being able to correct change in an amount of stroke caused by welding. In the method for adjusting the amount of stroke of a movable member of a fuel injection valve including a nozzle member having a seat face, a nozzle holder member to which the nozzle member is joined by welding, and the movable member having a valve seat portion for coming in contact with the seat face, the amount of stroke of the movable member is adjusted by plastically deforming a deformable portion provided to the nozzle holder member after joining the nozzle member and the nozzle holder member by welding.
