PROBLEM TO BE SOLVED: To obtain a piezoelectric gas jet generation device capable of effectively cooling aimed space (part) by vibrations of piezoelectric transducers. SOLUTION: The piezoelectric gas jet generation device has upper and lower variable displacement chambers formed by the piezoelectric transducers and a plurality of upper supply and exhaust pipes and lower supply and exhaust pipes respectively communicating with the upper and lower variable displacement chambers and respectively projected from an upper housing and from a lower housing for efficiently using displacement of air supplied and exhausted by vibrations of the piezoelectric transducers, wherein the upper supply and exhaust pipes and the lower supply and exhaust pipes are respectively projected in directions parallel to a plane direction of the piezoelectric transducers and parallel to each other in the same directions and the upper supply and exhaust pipes and the lower supply and exhaust pipes are arranged with their plane positions different from each other.
