Abstract: A connecting body for nails includes a large number of nails that are arrayed in parallel to each other at regular intervals, each including a shank portion welded to two wires respectively crossing the nails at two positions spaced apart from each other in a direction of an axial line of the shank portion so that the nails are connected to each other. A diameter of each of the two wires is set to be sufficiently smaller than a diameter of each of the nails. The shank portion of the each of the nails includes vertical ribs formed at a position of a welded portion on an outer periphery of the shank portion so as to protrude along the direction of the axial line of the shank portion. Outer surfaces of the two wires are welded to the vertical ribs of the nails.
