A ventilation system 1 includes: a housing 2 having at least one pair of ventilation holes 21; and a piezoelectric blower 3 attached to at least one of the pair of ventilation holes 21. The piezoelectric blower 3 is operative to vibrate a diaphragm by a piezoelectric element so as to produce air circulation through the ventilation holes 21. With this configuration, it is possible to produce forced convection while saving space, since the piezoelectric blower 3 has the shape of a thin plate. In addition, since the piezoelectric blower 3 continuously operates while being supplied with electricity, moisture can be discharged from the interior of the housing 2 to the outside in a short time. |
