Provided is a driving module, including: a tubular or cylindrical body to be driven (4); a cylindrical support (5) for housing the body to be driven therein; a pair of plate spring members (6, 7) for elastically holding the body to be driven so that the body to be driven is movable in a fixed direction relative to the support; and driving means (10) for driving the body to be driven against a recovering force of the plate spring members, in which the plate spring members includes the first plate spring member (6) positioned on a side which does not receive a force generated by the driving means and the second plate spring member (7) positioned on the opposite side of the body to be driven from the first plate spring member, a spring constant of the first plate spring member being larger than that of the second spring member.
