Abstract: An electromagnetic valve includes a valve casing, which has a valve hole, a spool valve in the valve hole, first and second output ports each communicating with the valve hole, first and second pressure introduction holes, which respectively communicate with the first and second output ports, first and second pressure sensors, which is respectively fitted in the first and second pressure introduction holes, sealing members, which are arranged between the respective pressure sensors and the pressure introduction holes, first and second substrates, on which the corresponding first and second pressure sensors are mounted, and a housing, which accommodates the first and second substrates, has the first and second pressure introduction holes, and is attached to the valve casing. The first and second substrates are arranged to be opposed to each other in a state of being upright in a direction perpendicular to the movement direction of the spool valve.
