Abstract:
A stirring device and an analyzing device for stirring a liquid retained in a vessel with sound wave. The Stirring device (20) comprises: a surface acoustic wave element (24) having sound generation section (24b, 24c) located on a piezoelectric substrate (24a) wherein the sound generation sections are electrically connected in parallel, and center frequencies of respective fundamental waves of the sound generation sections differ from each other, respective resonant frequency bands of the sound generation section are partially overlapped with each other, and origins of acoustic stream caused by sound wave radiated to the vessel from different sound generation section are located alternately; and a drive control section (21) for controlling a frequency of drive signal input to the surface acoustic wave element so that at least two sound generation sections of the plurality of sound generation sections generate sound wave simultaneously.
