る。[Effects of the Invention] As explained above, according to the present invention, a vibration source imparts fibrillating motion to the stirring body, which is a stationary stirring element, arranged in a conduit, thereby causing fluid to flow into the stirring blades. When the static stirring action is performed by repeating division and merging, the fibrillating motion imparts the desired vibration to the fluid, and as a result, the effectiveness of the static stirring mixing action can be significantly enhanced, especially when particle size A mixer device can be obtained which is extremely useful for fine mixing.
