PROBLEM TO BE SOLVED: To provide a nail driving machine for driving a double-headed nail, and a construction method of a wall heat-insulation structure using this driving machine. SOLUTION: In the driving machine 1, an upper side guide groove 21 and a lower side guide groove 22 parallel to each other are arranged on a guideway 15 in a nail magazine 8, and an upper side head part 3a and a lower side head part 3b of the double-headed nail 2 are, respectively, arranged in the upper side guide groove 21 and in the lower side guide groove 22 to transfer the double-headed nail 2 to a nail striking and pressing position P by making the double-headed nail 2 travel on the surface of the guideway 15. By using this driving machine 1, the double-headed nail 2 is driven so that a tip end reaches a pillar, and the lower side head part 3b reaches a load-bearing face material, and the upper side head part 3a reaches an outside heat-insulating material, respectively, thereby fixing a wall heat-insulated unit to a wall frame structure such as the pillar, to thereby construct a wall heat-insulated structure.
