ABSTRACT:
A piezoelectric gas jet generator includes a piezoelectric vibrator and upper and lower volume-varying chambers formed above and below the piezoelectric vibrator. In order to effectively use the movement of air supplied with the vibration of the piezoelectric vibrator, plural upper supply pipes and lower supply pipes communicating with the upper and lower volume-varying chambers and protruding from an upper housing and a lower housing are made to protrude in a direction parallel to the plane of the piezoelectric vibrator so as to be parallel to each other. Here, the upper supply pipes and the lower supply pipes are located at different planar positions.
