PROBLEM TO BE SOLVED: To suppress degrading of roundness of an insertion hole of a valve unit due to warp, which is a problem when miniaturizing a yoke of an electromagnetic valve, and thereby reduce magnetic transmission loss between the yoke and the valve unit.SOLUTION: An electromagnetic valve for fluid pressure control includes a coil 2, a yoke 3, and a valve unit. The valve unit includes a cylindrical guide of a magnetic material for covering an outer circumferential of a movable element. The yoke 3 is formed in a U-shape, and has a connection section 3a and folded portions 3b. Each of the folded portions 3b at both ends of the connection section 3a has an insertion hole 3c of a valve unit for inserting the cylindrical guide and a width narrowed part 3d which is formed by narrowing the width at a side continuing to the connection section 3a. The width W of the connection section 3a is smaller than the width W1 of a section in which the insertion hole of the valve unit is formed. |
