PROBLEM TO BE SOLVED: To provide a driving apparatus capable of positioning a driven body at a correct position by canceling the influence due to the external temperature. SOLUTION: The driving apparatus 50 to drive a driven body 60 between a first fixing part 70 and a second fixing part 72 comprises a bias spring 80 to provide a bias power to the fixing part 72 by connecting the driven body 60 to the fixing part 72, an energized-type shape-memory alloy member 90 to move the driven body 60 to the fixing part 70 against the bias force of a bias spring 80 by connecting the driven body 60 to the fixing part 70 and applying an electric current and a non-energized type shape-memory alloy member 100 by connecting the driven body 60 to the second fixing part 72 and not applying the electric current normally.
