A driving apparatus (100) is provided with: a first base part (110-1); a second base part (110-2); a first elastic part (120a-1, 120b-1); a driven part (130); a second elastic part (120a-2, 120b-2); and an applying part (160) which is configured to apply, to the second base part, an excitation force for rotating the driven part such that the driven part rotates while resonating around the axis along the one direction, at a resonance frequency determined by the second elastic part and the driven part, the applying part applies the excitation force such that the second base part vibrates and deforms in a shape of stationary wave along the another direction and the deformational vibration becomes resonance, the resonance frequency at which the second base part resonates is same as a resonance frequency of the driven part. |
