Abstract
In order to make it possible to increase a diameter and output thereof, a diaphragm structure is provided that has low repulsiveness, can be largely deformed to increase a stroke even without being applied with a large force from an actuator, and is unlikely to give rise to a defect or fault even when formed thin, and a fluid control valve is provided with the diaphragm structure and the actuator that presses the diaphragm structure, wherein the diaphragm structure is provided with: a protruding part that is formed in a tubular shape and pressed by the actuator; a brim part that spreads from a base end of the protruding part outward with respect to the protruding part; and a support part that is formed on an outer circumference of the brim part and attached to another member, and the brim part is formed in a film shape.
