Abstract
Provided is a piezoelectric module capable of attempting further miniaturization. In the piezoelectric module, a resonance point is excluded from a frequency band of a transmitted signal to avoid shortening of a signal transmission distance, thereby attempting improvement in stability of communication. In addition, since a resonance space is not provided, further miniaturization may be easily attempted.
