Abstract
A fluid control apparatus includes a valve and a pump. The valve has a valve chamber. The first main plate has a first aperture through which the valve chamber communicates with the outside, and the second main plate has a second aperture through which the valve chamber communicates with the outside. The valve further includes a valve diaphragm disposed inside the valve chamber. The valve diaphragm is configured to switch the communication state. The pump includes a piezoelectric device. The pump has a pump chamber. The pump chamber communicates with the valve chamber through the second aperture. In addition, in flexural vibration of the vibration unit, a frequency coefficient of the first main plate is greater than a frequency coefficient of the second main plate.
