A fluid control device includes a valve, a pump and a film valve. The valve includes a first main plate, a second main plate, a first side plate, and a valve chamber. The first main plate has a first vent hole, and the second main plate has a second vent hole. The film valve is disposed in the valve chamber. The first vent hole is positioned in a central region of the valve chamber, and the second vent hole is positioned in an outer end region of the valve chamber. The film valve is positioned between the first vent hole and the second vent hole. The film valve is fixed to the second main plate in a state in which an end portion on a side of the outer end region or an end portion on a side of the central region is capable of vibrating.
