Abstract
A driving device and driving device manufacturing method that ensure stable fixing of an SMA, without causing difficulties in downsizing the device, and without adversely affecting the performance of the SMA. A driving device equipped with a string-shaped shape memory alloy as a drive source includes a base member constituting a basis of the driving device, and a rod-like member which penetrates the base member and is made of the metal fixed onto this base member. The rod-like member is caulked on one end of this rod-like member so that the aforementioned shape memory alloy is pinch-held in-between, whereas power-feeding members to apply current to the shape memory alloy are arranged on the other end of the rod-like member.
