PROBLEM TO BE SOLVED: To provide a valve device less susceptible to the influence of fluid pressure and excellent in terms of the energy required to drive a valve body and in terms of response. SOLUTION: A valve device 1 is configured so that the inside of a tubular body section 310 having a coil 33 wound thereon of a coil bobbin 31 is utilized as a flow path 10, and so that a movable body 7, which is provided with a permanent magnet body 72, is disposed as the valve body within the flow path 10. Further, a stationary body 2 comprises as a pressing member a magnetic body 25 which presses the movable body 7 toward a fluid outlet 12 to close the fluid outlet 12 by an end of the movable body 7. Further, the movable body 7 is separated from the fluid outlet 12 by propulsion force which acts on the movable body 7 when an electric current is conducted to the coil 33 with the fluid outlet 12 closed, and as a result, the fluid outlet 12 is opened.
