Provided is a fuel injection valve capable of stroking a valve body in two stages of large and small strokes and improving responsiveness of a valve opening operation. Therefore, a first mover is attracted to a magnetic core . A second mover is formed separately from the first mover , and is attracted to the magnetic core on an inner diameter side of the first mover . A valve body has a flange portion on an upstream side of the second mover . A spacer forms a gap (void g) in an axial direction between the flange portion and the second mover in a valve closed state.
