Provided is a fluid transportation device and a fluid transportation method in which a transported fluid such as a gas or a liquid can be ejected into a space from an ejection unit and transported locally to a target location distant from the ejection unit while minimizing scattering. The transporting fluid is ejected from an ejection port into a space and thereby forms vortex rings, and the transported fluid is fed to the outside of the transporting fluid at a speed that is lower than that at the center of the transporting fluid, whereby the transported fluid is directly accommodated in the vortex rings formed by the transporting fluid moving in a rolling motion at the ejection port, and transported together with the vortex rings.
