PROBLEM TO BE SOLVED: To provide an electromagnetic valve capable of reducing power consumption when operating an armature stopped in a neutral position. SOLUTION: This electromagnetic valve is provided with an electromagnetic actuator 32 for driving both of opening/closing operation and a side core 33 near a side of the armature 24. In the side core 33, a part corresponding to a neutral position of the armature 24 is provided with first clearances 34 and 35, and provided with second clearances 36 and 37 in both vertical sides of the first clearances so that the armature 24 is tilted to be separated in a displacing direction from the neutral position thereof, as it separates more from an armature stem 19. When a lower coil 31 is electrified in the condition wherein the armature 24 is stopped in the neutral position, these clearances 34-37 deflect direction of a flux, which passes through the armature 24 and the side core 33 in order, along the clearances 34-37. With this deflection, divided force directing to a lower core 26 is generated in the electromagnetic force. COPYRIGHT: (C)2006,JPO&NCIPI
