To provide an electromagnetic valve which can prevent damage caused by stress of a buffer member.SOLUTION: An electromagnetic valve 1 includes: a solenoid 2 having a case 24; a passage member 4; and a columnar valve body 5 which is housed in a valve body housing part 49 of the passage member 4 and moves with a plunger 22 of the solenoid 2 to open or close a passage. A sheet member 62 with which the plunger 22 contacts is disposed at the case 24 of the solenoid 2. The sheet member 62 has: a core part 621 with which the plunger contacts; and multiple protruding parts 623 protruding from an outer peripheral surface 622 at the radial outer side of the core part 621 to the radial outer side.SELECTED DRAWING: Figure 4 【課題】緩衝部材の応力による損傷を防止することができる電磁弁を提供すること。【解決手段】電磁弁１は、ケース２４を有するソレノイド２と、流路部材４と、流路部材４の弁体収容部４９内に収容され、ソレノイド２のプランジャ２２とともに移動することにより、流路を開閉する柱状の弁体５とを備える。ソレノイド２のケース２４にはプランジャ２２が接触するシート部材６２が配置されている。シート部材６２はプランジャが接触するコア部６２１と、コア部６２１の径方向外側の外周面６２２から径方向外側に突出する複数の突出部６２３とを有する。【選択図】図４
