PROBLEM TO BE SOLVED: To provide a solenoid driven valve for providing sufficiently large driving force. SOLUTION: This solenoid driven valve 10 has a driving valve 14 having a stem 12, a lower disc 20 and an upper disc 30 having arm parts 21 and 31 and extending toward the other ends 23 and 33 rockingly supported by a disc support base 51 from one ends 22 and 32 connected to the stem 12, and an electromagnet 60. The electromagnet 60 has a core 61 oppositely arranged in the arm parts 21 and 31, and a coil 62 revolved around the core 61. The electromagnet 60 forms magnetic circuits 102 and 101 passing through the core 61 and the arm parts 21 and 31 by making an electric current flow to the coil 62. The solenoid driven valve 10 has permanent magnets 72 and 71 having the magnetic axis along the magnetic circuits 102 and 101 and arranged so as to act on a magnetic flux flowing to the magnetic circuits 102 and 101.
