PURPOSE: An energy harvesting apparatus is provided to widen the frequency band of an electric output by changing vibrating energy into electric energy. CONSTITUTION: An energy harvesting apparatus includes a cantilever (110), a movable mass (140), an elastic member (130), and an electric energy generator (150). One end of the cantilever is fixed to a structure (1). The cantilever generates a vibration dislocation by receiving a vibration from the structure. The movable mass is arranged on the other end of the cantilever and moves in the length direction of the cantilever. The elastic member fixes the movable mass to move on the cantilever. The electric energy generator is arranged on the cantilever and changes the vibrating energy of the cantilever to electric energy by being deformed when the cantilever generates the vibration dislocation.
