An electromagnetic valve generally has a housing, a valve element, an electromagnetic driving portion and a filter. The housing forms a fluid flow passage therein. The valve element is installed in the housing to control a flow of a fluid through the fluid flow passage. The electromagnetic driving portion is installed in the housing to generate a magnetic attraction force when it is energized to actuate the valve element. At least a part of the electromagnetic coil is within the fluid flow passage. The filter is installed in the fluid flow passage on an upstream side of the at least a part of the electromagnetic driving portion to filtrate the fluid flowing through the fluid flow passage.
