Abstract
An electromagnetic valve includes: a solenoid having a plunger movably supported along an axis Odirection; a flow path member having a fluid passage flow path and a valve element housing portion; and a valve element in a columnar shape that is disposed in the valve element housing portion, is movable along the axis Odirection together with the plunger, and can switch between an open state and a closed state. The flow path member has an abutment portion that abuts on the valve element in the valve element housing portion, and a biasing member that biases the valve element. The valve element has an enlarged-diameter portion on the radially outer side. The enlarged-diameter portion has an opposing surface portion opposing the abutment portion at least in the axis Odirection. The opposing surface portion is in contact with the abutment portion in the open state.
