Abstract
A fuel injection valve configured to inject fuel from an injection hole includes: a coil that is configured to generate a magnetic flux when the coil is energized; a stationary core that forms a portion of a flow passage, which is configured to conduct the fuel to the injection hole, wherein the stationary core is configured to become a passage of the magnetic flux; a movable core that is configured to be attracted toward the stationary core when the movable core becomes a passage of the magnetic flux; a passage forming portion that is placed on a downstream side of the stationary core and forms a portion of the flow passage; and a covering portion that covers a stationary boundary, which is a boundary between the passage forming portion and the stationary core, from a flow passage side of the stationary boundary where the flow passage is located.
