ドバルブ。 A fixed core 3 is disposed inside the outer core 1, and the movable core 4 is held in contact with the fixed core 3 by the force of a permanent magnet 8 against the biasing member 6. When energized, the acting force of the permanent magnet 8 is made smaller than the biasing force of the biasing member 6 to separate the movable core from the fixed core 3, and the valve body 7 provided on the movable core 4 closes the fluid flow path. 12 and 13, a magnetically sensitive switch 14 is disposed at a contact portion between the fixed core 3 and the movable core 4, and the movable core 4 is in contact with the fixed core 3. A solenoid valve characterized in that the magnetic force of the permanent magnet 8 acting on the magnetically sensitive switch 14 changes depending on when the switch is separated from the switch.
