To provide a solenoid valve which can enhance the assembling workability of a seal member.SOLUTION: In a solenoid valve having an annular flange part 2A expanded in a radial direction of an opening part which is opened at an end face in an axial direction, also comprising a valve case for accommodating a valve body therein, and attached with an annular seal member 6 in an annular recessed groove 4 which is formed at one end face in the axial direction of the flange part 2A of the valve case, a penetration hole part 5 penetrating the flange part 2A in the axial direction, and a connection part 7 for connecting the penetration hole part 5 and the annular recessed groove 4 are arranged at the flange part 2A, the penetration hole part 5 has a diameter-contracted part 5C, and the seal member 6 comprises an annular part 6A attached into the annular recessed groove 4, and a salient part 6B salient in at least the axial direction with respect to the annular part 6A, and penetrating the penetration hole part 5. A diameter-expanded part 6c having an outside diameter φD1(>φd2) which is larger than an inside diameter φd2 of the diameter-contracted part 5C of the penetration hole part 5 are arranged at the salient part 6B.SELECTED DRAWING: Figure 3 【課題】シール部材の組付作業性を高めることができるソレノイドバルブを提供する。【解決手段】軸方向端面に開口する開口部の径方向に広がる環状の鍔部２Ａを有し、内部に弁体を収容したバルブケースを備え、該バルブケースの鍔部２Ａの軸方向一端面に設けられた環状凹溝４内に環状のシール部材６を装着したソレノイドバルブにおいて、鍔部２Ａには、該鍔部２Ａを軸方向に貫通する貫通孔部５と、該貫通孔部５と環状凹溝４とを連結する連結部７と、を備え、貫通孔部５は、縮径部５Ｃを有し、シール部材６は、環状凹溝４内に装着される環状部６Ａと、該環状部６Ａに対して少なくとも軸方向に突出して貫通孔部５を貫通する突起部６Ｂとを備え、該突起部６Ｂに、貫通孔部５の縮径部５Ｃの内径φｄ２よりも大きな外径φＤ１（＞φｄ２）を有する拡径部６ｃを備える。【選択図】図３
