A driving apparatus (100t) is provided with: stage portion (130) which can be displaced; a first elastic portion (120-1) whose one end is connected to the stage portion and which has elasticity to displace the stage portion in one direction; a driving source device (180), to which other end of the first elastic portion is connected, comprising: a first applying device (181) for applying an excitation force for displacing the stage portion such that the stage portion is resonated in the one direction at a resonance frequency determined by the stage portion and the first elastic portion; and a second applying device (182) for applying a driving force for displacing, in a stepwise manner or in a continuous manner, the stage portion in other direction; a second elastic portion (120-2) whose one end is connected to the driving source device and which has elasticity to displace the stage portion in the one direction; a third elastic portion (120-3) whose one end is connected to other end of the second elastic portion and which has elasticity to displace the stage portion in the other direction; and a base portion (110) to which other end of the third elastic portion is connected.
