An electromagnetic valve includes a flow passage, a valve member, an actuator having a coil and a movable core, an intermediate member, a connecting member, a housing, and a dividing unit. The housing includes a hollow part between the housing and the actuator. The hollow part communicates with the flow passage. The dividing unit includes a through hole which passes through the dividing unit in its axial direction. The dividing unit divides the hollow part between a communicating chamber that is capable of communicating with the flow passage, and a cancel chamber that is cut off from an outside thereof. The intermediate member includes a communicating passage between the intermediate member and the movable core. The communicating passage communicates between the flow passage and the cancel chamber via the through hole and the communicating chamber.
