摘要:
A small-sized and highly efficient drive apparatus, an image pickup unit and an image pickup apparatus are provided, by using a polymer actuator that is small in size and has high speed of response and has high degree of freedom for arrangement, and by realizing an actuator having excellent assembly simplicity. By being provided with a polymer actuator and by moving objects to be driven such as an image pickup device, a lens, an image pickup optical system and a lens barrel unit by the use of the actuator, an actuator that is small in size and has the high speed of response, a high degree of freedom for arrangement and excellent assembly simplicity can be provided, which makes it possible to provide a small-sized and highly efficient drive apparatus, an image pickup unit and an image pickup apparatus.
