To easily and surely peel off only a metal foil.SOLUTION: While a shielded wire W is positioned with an insertion jig in front of a peeling jig, a portion is inserted where a metal foil Wb at the tip of the shielded wire is exposed in a wire insertion hole 11 of the peeling jig through a center hole 21 of the insertion jig 20. Air A1 is blown from an opening on the other end surface side of the peeling jig toward the tip of the shielded wire to inflate the metal foil while separating the metal foil from a wire core. A notch Wb2 is made from the side into the metal foil Wb1 exposed to the outside in a predetermined gap N between one end surface 12 of the peeling jig and the end surface 24 of the insertion jig and inflated by blowing air, and the notch is used as a starting point to cut the metal foil. As a result, the metal foil Wb exposed to the outside from a removed sheath and the tip of a braid is stripped from the wire core Wa.SELECTED DRAWING: Figure 1
