An electromagnetic actuator is provided that can achieve reduction in size, weight and cost by a simple configuration, and a solenoid-valve device provided therewith. The electromagnetic actuator section includes fixed pole pieces that a middle of three fixed magnetic poles has, and coils wound around the fixed pole pieces. The coils are wound in the same winding direction. The needle has first and second stabilization points corresponding to the fixed magnetic poles on both sides in the axial direction, and a third stabilization point corresponding to the middle fixed magnetic pole, as stabilization points at which a stationary state can be maintained when the coil is unenergized. |
