Valve element and method for manufacturing valve element

A valve element for controlling flow of a fluid, the valve element comprising:

• a first movable electrode portion including a fluid introduction port through which the fluid flows;
• a second movable electrode portion including a discharge port through which the fluid is discharged, the second movable electrode portion being disposed on one surface side of the first movable electrode portion to cover the fluid introduction port, with an interval between the second movable electrode portion and the first movable electrode portion;
• a spacer portion configured to secure the interval between the first movable electrode portion and the second movable electrode portion;
• and
• a frame portion configured to form a back chamber that communicates with the fluid introduction port on another surface side of the first movable electrode portion and configured to support the first movable electrode portion, wherein
• the first movable electrode portion and the second movable electrode portion is drawn together by an electrostatic attractive force generated by applying a voltage to each electrode of the first movable electrode portion and the second movable electrode portion to seal the fluid introduction port.
