PROBLEM TO BE SOLVED: To provide a solenoid driven valve improved in response. SOLUTION: The solenoid driven valve V has an electromagnetic linear driving device 10. The electromagnetic linear driving device 10 has a driving part 20 and a movable part 30 driven by the driving part 20. The driving part 20 is equipped with a magnetic pole part having a magnetic pole member which is constituted so that the coil area is enlarged by downsizing the member as an upper magnetic pole part (a first magnetic pole part 23) and a lower magnetic pole part (a third magnetic pole part 25).
