PURPOSE: A power generation device using piezoelectric elements is provided to improve the efficiency of s piezoelectric element by increasing vibration frequency due to external force. CONSTITUTION: A vibration plate is vibrated by external impact or pressure. A supporting plate(200) is formed in the lower side of the vibration plate. A piezoelectricity module(300) comprises a piezoelectric element. A vibration generator(400) is fixed to the piezoelectricity module. A converting part changes the electrical energy generated from the piezoelectric element.
