A normally open solenoid valve (10), includes: a coil (12); a fixed core (20) that is excited when the coil (12) is energized, the fixed core (20) having a through hole (22) and an opening formed at an end of the through hole (22); a valve seat (42) disposed at the opening; a valve element (30) inserted through the through hole (22), the valve element (30) including a valve part (34) for coming into contact with the valve seat (42) and a roughly columnar shaft part (24) extending from the valve part (34); and a movable core (28) that pushes and moves the valve element (30). The shaft part (24) has a plurality of sliding portions (31,33) that are slidable on the inner surface of the through hole (22) and are formed to be spaced in an axial direction of the shaft part (24) and a narrowed portion (32) having an outer diameter smaller than the sliding portions (31,33) between the plurality of sliding portions (31,33). <IMAGE> |
