PROBLEM TO BE SOLVED: To increase an air intake/exhaust amount of an intake/exhaust port in an air flow generation part in which air flow occurs by changing a content volume.SOLUTION: An air blower 1 includes an air flow generation unit 10 formed into a hollow thin plate shape in which parts other than a suction/exhaust port P are sealed, and the air flow generation unit 10 performs suction/exhaust from the suction/exhaust port P by changing a content volume with a vibration plate 11, the vibration plate vibrating in a thickness direction with a piezoelectric effect of a piezoelectric element 12. In the air blower 1, a front region E of the suction/exhaust port P is sectioned into a positive pressure range E1 and a negative pressure range E2 in a width direction by a partition plate 21 of a section part 20.SELECTED DRAWING: Figure 1 |
