Beschreibung
Zusammenfassung:	To provide an electromagnetic valve that can prevent damage due to wear of a valve element and a case of a solenoid, or occurrence of a striking sound when a valve is opened. An electromagnetic valve includes a solenoid having a case, a flow path member, and a columnar valve element that is housed in the valve element housing portion of the flow path member and moves with a plunger of the solenoid to open and close a flow path. A first seat member in contact with the plunger is disposed on the valve element, and a second seat member in contact with the plunger is disposed on the case of the solenoid. An elastic modulus of the first seat member is larger than an elastic modulus of the valve element, and an elastic modulus of the second seat member is smaller than an elastic modulus of the case.
