A solenoid valve includes an inner stator and an outer stator that are part of a magnetic circuit. An armature is attracted toward the inner stator when a coil is energized. A spring biases the armature in a direction away from the inner stator. A rod is integrally formed with the armature and integrally reciprocates with the armature. A guide guides reciprocation of the rod. A valve operates by following the rod to open and close a fuel/liquid passage. The spring and sliding portions between the rod and the guide are arranged within a recess portion formed in the inner stator and arranged in parallel to each other while overlapping in the axial direction.
