Abstract
In an electromagnetic valve, a seat member has a protruding portion having two parallel surfaces provided in the seat member. When the seat member is fixed to the base member by inserting molding, the two parallel surfaces of the protruding portion may be put between projecting portions of a pin of a molding die. As a result, the fluid passage of the seat member may be easily positioned to correspond to an opening of the base member. Further, after molding, the seat member may be prevented from rotating in the base member since the parallel surfaces are partly covered by resin of the base member.
