To provide a piezoelectric fan having a vibration-proof apparatus by incorporating the vibration-proof apparatus for preventing vibration necessary for a piezoelectric fan from being transmitted to others even if no vibration isolator, or the like, is used, and for thinning the size of the piezoelectric fan itself.

In the piezoelectric fan having a vibration-proof apparatus, a vibration-proof unit composed of the piezoelectric unit, a cymbal spring and a weight is mounted to a base, and an upper lid is mounted to the vibration-proof unit.
