PROBLEM TO BE SOLVED: To provide a solenoid-driven valve capable of appropriately cooling a electromagnetic coil of a electromagnetic actuator for opening and closing drive without causing insufficient cooling and overcooling. SOLUTION: A solenoid-driven valve 19 is provided with the actuator for opening drive 46 and the electromagnetic actuator for closing drive 43 displacing an armature stem 25 in an axial direction by applying electromagnetic force generated with accompanying electricity carry to the coils 45, 42 on an armature 39 and driving a valve 15 open and close, and a pair of cooling means provided on the each electromagnetic actuator 46, 43 and cooling the coils 45, 42. Lubricating oil 38 for lubricating both an upper part and a lower part sliding bearing 37, 36 is used as a cooling means. Cooling capacity of the cooling means on a side of the electromagnetic actuator for opening drive 46 is set larger than cooling capacity of the cooling means on a side of the electromagnetic actuator 43 for closing drive 43.
