Summary:In a fuel injection valve, a movable structure includes: a movable core that includes a first attractive surface and a second attractive surface, which are configured to be attracted toward at least one stationary core when a coil is energized; and an elongated shaft member that has a length, which is measured in a moving direction of the movable structure and is larger than a length of the movable core, which is measured in the moving direction. A modulus of longitudinal elasticity of the elongated shaft member is larger than a modulus of longitudinal elasticity of the movable core.
