To provide a solenoid valve capable of miniaturizing or saving weight.SOLUTION: A solenoid valve includes a sleeve 20, a spool 30, a spring member 80 and a solenoid 70. The sleeve 20 has a discharge port 24, an output port 23 and an input port 22 in this order from the spring member 80 side along an axial direction. The spool 30 has a first land part 31 having a first diameter L1 and for opening/closing between the discharge port 24 and the output port 23 and a second land part 32 having a second diameter L2 smaller than the first diameter L1 and for opening/closing between the output port 23 and the input port 22 in this order from the spring member 80 side along the axial direction. When the solenoid 70 is in a non-excited state, the output port 23 and the input port 22 are connected and the output port 23 and the discharge port 24 are cut off.SELECTED DRAWING: Figure 1 【課題】小型化または軽量化が可能な電磁弁を提供する。【解決手段】スリーブ２０と、スプール３０と、バネ部材８０と、ソレノイド７０と、を備え、スリーブ２０は、軸方向に沿ってバネ部材８０側から順に、排出ポート２４と、出力ポート２３と、入力ポート２２とを有し、スプール３０は、軸方向に沿ってバネ部材８０側から順に、第１の径Ｌ１を有し排出ポート２４と出力ポート２３との間を開閉する第１ランド部３１と、第１の径Ｌ１よりも小さい第２の径Ｌ２を有し出力ポート２３と入力ポート２２との間を開閉する第２ランド部３２と、を有し、ソレノイド７０が非励磁状態にあるとき、出力ポート２３と入力ポート２２との間が繋がり、出力ポート２３と排出ポート２４との間が遮断される、電磁弁。【選択図】図１
