To acquire a large drive distance and realize miniaturization.

A driving apparatus (1) is provided with a reference member (11), a moving member (12), connected to the reference member through at least two beams (14, 15), movable relative to the reference member as a reference position and extending, in a direction different from the moving direction, and an extending/contracting member (13), connected to the reference member at one end and extending or contracting. At least two beams have constriction sections (141, 142, 151, 152) narrower than peaks or sections other than the proximal sections of the peaks at the peaks or the tip sections of the peak of a parallelogram, including at least a portion of two beams. The other end of the extending/contracting member is connected to the one beam, between the constriction section adjacent to the reference member in the one beam, and the constriction section adjacent to the moving member in one beam.
