Abstract
A diaphragm pump includes a piezoelectric member, a diaphragm having surfaces, and a supporting member. The piezoelectric member deforms when a voltage is applied. The diaphragm deforms in response to deformation of the piezoelectric member. The supporting member supports the diaphragm. A space is formed between the diaphragm and the supporting member. Fluid is made to flow by changing a volume of the space by deforming the diaphragm. The surfaces of the diaphragm face the space and include a first surface that deforms in response to deformation of the piezoelectric member and include a second surface not connected to the first surface. The diaphragm bonds to the supporting member with the second surface.
