Abstract
Official abstract text for this publication.
A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate with first and second main surfaces, a frame plate surrounding the vibrating plate, and a link portion linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole faces the second main surface of the vibrating plate, being fixed to the frame plate. At least a portion of the vibrating plate and the link portion are thinner than the thickness of the frame plate so that the surface of the portion of the vibrating plate and the link portion, on the side of the flexible plate, can separate from the flexible plate.
