PROBLEM TO BE SOLVED: To provide a solenoid valve capable of making controllability of valve opening suitable with a simple structure.SOLUTION: A plunger 20 comprises an outside plunger component 21 arranged in a reciprocated manner in a direction of laterally penetrating a flow passage, and an inside plunger component 22 arranged in a slidable manner in an axial direction inside the outside plunger component 21. Then, the respective plunger components 21, 22 are individually energized with springs 41, 42 separately arranged in parallel. Further, the outside plunger component 21 is formed with a magnetic body, and the inside plunger component 22 is formed with a non-magnetic body.SELECTED DRAWING: Figure 1 【課題】 簡易な構成で弁開度の制御性を好適なものとすることが可能な電磁弁を提供すること。【解決手段】 プランジャ２０を、流路を横貫する方向に往復動可能に配置される外側プランジャ構成体２１と、該外側プランジャ構成体２１内にて軸方向にスライド可能に配設される内側プランジャ構成体２２とで構成する。そして、各プランジャ構成体２１，２２を並列に配置された別個のスプリング４１，４２にて個別に付勢する。さらに、外側プランジャ構成体２１を磁性体にて形成するとともに内側プランジャ構成体２２を非磁性体にて形成する。【選択図】図１
