To provide an electromagnetic valve which can prevent damage caused by wear while preventing increase of the weight of a valve body.SOLUTION: An electromagnetic valve 1 includes: a solenoid 2 having a plunger 22 which is supported so as to be movable along an axis O1 direction; a passage member 4 having a fluid passing passage 46 and a valve body housing part 49; and a valve body 5 which is disposed at the valve body housing part 49 and may move along the axis O1 direction with the plunger 22. The valve body 5 has: a body part 51; a valve part 53 which opens or closes the fluid passing passage 46 in conjunction with movement of the plunger 22; and a rod-like pin 55 which penetrates through the body part 51 along the axis O1 direction. The body part 51 is provided with at least one opening 56 which is open in a direction orthogonal to the axis O1 direction and from which the pin 55 is exposed.SELECTED DRAWING: Figure 3 【課題】弁体の重量の増大を防止しつつ、摩耗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、軸Ｏ１方向に沿って移動可能に支持されたプランジャ２２を有するソレノイド２と、流体通過流路４６と弁体収容部４９とを有する流路部材４と、弁体収容部４９に配置され、プランジャ２２とともに軸Ｏ１方向に沿って移動可能な弁体５とを備える。弁体５は、本体部５１と、プランジャ２２との移動に伴って流体通過流路４６を開閉する弁部５３と、本体部５１を軸Ｏ１方向に沿って貫通する棒状のピン５５とを有する。本体部５１には、軸Ｏ１方向と直交する方向に開口し、ピン５５が露出する少なくとも１つの開口部５６が設けられている。【選択図】図３
