PROBLEM TO BE SOLVED: To improve reliability with simple constitution and facilitate assembly in a drive module and an electronic device equipped with the same. SOLUTION: The drive module 1 includes: a lens frame 4 having an upper side fixing pin 13A and a lower side fixing pin 13B; a cylindrical module frame 5 housing the lens frame 4 movably in a fixed direction and having an upper side fixing pin 14A and a lower side fixing pin 14B; an upper leaf spring 6 and a lower leaf spring 7 stacked at the end of the cylinder of the module frame 5 and the end of the lens frame 4 while they are inserted through the respective fixing pins in the same direction respectively, and applying energizing force in the fixed direction to the lens frame 4; and an SMA wire 10 stretched on the outer periphery part of the cylinder of the module frame 5 and driving the lens frame 4 against the energizing force of the upper leaf spring 6 and the lower leaf spring 7. The upper leaf spring 6 and the lower leaf spring 7 are fixed by caulking the tip parts of the upper side fixing pins 13A and 14A, and the lower side fixing pins 13B and 14B.
